Fortigate traffic not hitting policy. Not at all, there is a default route.

Fortigate traffic not hitting policy 101 PC which resides in Subnet_B: Policy why the traffic didn&#39;t hit the specific SD-WAN rule with ISDB. Scope . ) Send the traffic to the non-functioning app or website. What is the best practice to check why traffic is not hitting this tunnel or policy? P. The Count column and the policy monitors In firewall policies try using the policy lookup tool at the top, it should show which policy it is hitting. Scope FortiGate. I've checked the logs in the GUI and CLI. 2 and above local traffic sent from the fortigate does not follow sdwan rules. S I have access only to my side of tunnel. For example: config firewall vip edit "vip" set extip 10. Enable Disk logging or set the log location as FortiAnalyzer or the Disk. Then the DNATed packets that are not matched by a VIP policy are matched with the general policy where they can be explicitly dropped and logged. This article describes how to solve a VIP issue when it is not hitting the correct policy. IP 1. 254 If server2 traffic is hitting policy 15 then policy 20 isn' t catching it. When the authentication is disabled on interface then traffic will move from correct policy. 5, and I had the same problem under 6. For example: An SD-WAN rule has been created as below: The source is 'all' and the destination is '1. Solution There are three attributes that can be configured in the SD-WAN service with ISDB: internet-service-custom. Starting in 6. I am trying to cap my DMZ interface and for some reason am struggling with it. Use the following command to trace specific traffic on which firewall policy it will be matching: diag firewall iprope lookup <src_ip> <src_port> <dst_ip> <dst_port> <protocol> <Source interface> Example scenario: The FortiGate was configured with 2 specific firewall policies as below: show firewall policy config firewall The "to" and "from" ip addresses for that policy are both a /32 not in the 10. 240. 101. Regards, Jerry 85 0 . Optional: This is possible to create deny policy and log traffic. Now, I am able to see live Traffic logs in FAZ, ok. If traffic is NOT hitting your policy, than "Stop" and don't proceed until you ensure that any other network routing or filtering problems has been fixed. diag debug flow show console enable. 100. Below are the steps to match the source-ip to a policy to analyze further for that source host. When configuring an SD-WAN service with an ISDB n Interesting my 61 at home shows active sessions on the SPU and the policy view shows almost all traffic across the expected policies as hitting the SPU. Unlike ipv4 policies there is not default implicit deny policy. Edit the policies controlling the traffic you wish to log. Thnx! FortiGate. By default, FortiGate will not generate the logs for denied traffic in order to optimize logging resource usage. internet-service-app-ctrl. ) ngfwid=0 . Check Logging Settings: Make sure that the logging settings for your policies are configured to include the Policy ID in the logs. I made very specific rules for the 192. In FortiOS version 5. The following policy should allow all traffic from the 100. Case 1: When only a traffic shaping-policy is used. This is a real case How can I verify that traffic is being accepted by (or hitting) a security policy? Use the security policy list Count column and the policy monitors. When an IPsec VPN tunnel is being established but traffic is not flowing through it, and no changes in FortiGate configuration have been made, then one has to perform packet captures of encapsulating security payload (ESP) packets (i. 2 and below. From the internet as from the guestnetwerk. A traffic shaping policy can be split into two parts: Options Fortigate rules not hitting Hi guys The thing is, if the rules are not being hit even after the policy has been pushed. IPsec VPN tunnels with FortiGate. 1 are from an hour earlier when i tried deleting the allow policy, tested pings, then recreated the policy. 168. If the menu does not display the traffic shaping settings, go to System > Feature Visibility and enable Traffic Shaping. edit 1. Now, I have enabled on all policy's. For now, however, all sessions will First to redirected traffic from Subnet_B via WAN2 only, and second policy to stop Policy Routing for traffic originated from Subnet_B. Solution: In this example, a policy has been created to allow all traffic from port 2 to port 1 In the ASA it is possible to shun an IP when x ammount of policy violations occured. If it doesn't hit any it is likely a route missing or confused. 129 Interface Generally "accept" policy 0 is local-in traffic. 4', but there is how to handle an issue where the Internet is not working with one of the SD-WAN member when IP pool is called in the policy. This might be relevant: I recently changed my FortiGate from standalone to Fabric Root. - To check the mac address on the pc, open the command prompt and enter 'ipconfig/all'. 0 I need to block traffic to certain websites and domains. 2. Solution Configuring the FortiGate with an ‘allow all’ traffic policy is very undesirable. From the internet this website is accessable. One webserver is on 200. Solution When initiate a traffic from Internet to the LAN segment is initiate (behind FGT), the traffic enters through one interface and it is possible to observe the reply traffic going out of a different interface than the original incoming interface (if Policy from Zone (with vlan10 in it) to VPN tunnel configured, Static Route (with subnet I try to reach, and VPN interface configured) also. In the above scenario, this was faced because there was VIP configured hence the static route configured was not taken into account. Hello, I have some traffic hitting Implicit Deny, even tho the Allow Policy seems to be correct: Logs: Rule: Found this: Traffic dropped by &#39;implicit deny pol - Fortinet Community, but everything shown is ok here. 0. I then created a firewall rule like this: Source zone: LAN Source address: any Dest Zone: WAN Dest address: any Application: any Service/URL Catego Then, I've created a IPv4 policy to forward traffic from my WAN port to the VIP Group, allowing all services, enabling the NAT and logging traffic . Note that logging of this can be a little weird, at least on the 6. My fortigate 100d is not forward traffic between Guestlan and lan. ]4 is gets 5 Policy violations in 60 seconds. I'm just trying to and hitting policy 0 because you don't (obviously) have policies to Fortigate rules not hitting Hi guys The thing is, if the rules are not being hit even after the policy has been pushed. diag debug disable. edit 5. This might be relevant: I recently changed my FortiGate from standa Hi all , New to Fortigate, can anyone tell me if you can see what policy a packet hits first ? the firewall im nor managing has ,alot of policies most of them redundant, i would like a sort of sniffer to see what Policy was use to either accept or dent the packet on CLI. Firmware is 6. A tracert to 8. Edit the policy from GUI and do not edit any existing settings, click on 'OK' Scope. 202 IP towards the internet. Admin Users UI Method: User account has Auth Type &#61; LDAP. - outbound policies need to have NAT enabled (simple NAT to interface address will do). P. 3, we are seeing traffic - randomly - bypassing the policy that should allow it and the hit the implicit deny policy (and get denied) . The only hits for source ip 10. Solution The traffic being denied by policy 0 since captive portal was enabled on interface level. To catch these packets, enable match-vip in the general policy. Fortianalyzer 1000B with version 4. To do this: Log in to your FortiGate firewall's web interface. I need to replace that static route with a policy route, however, due to a conflicting IP range. The traffic from the same source to the same destination will not hit 2 policies randomly as it flows a top-down approach and will hit the topmost matching policy always. source 172. You can check only 3 parameters: source IP, destination IP and service. disable npu-offload on the VPN (I think only phase-1 has this option) and the policies involved I called support and they did support things -- after much effort they showed that a ping from site A was being transmitted to site B, the reply was being encoded and transmitted back, but was not appearing to reach site A. This means local traffic does not have an associated policy ID unless user-defined local policies have been configured. diag debug enable. This can be verif If this happens, the packet is silently dropped and therefore not matched with the general policy at the bottom of the policy list. When using FQDN objects in the policy, FW will run DNS queries for the provided FQDN and put the first N IPs from the dns reply (not sure what was the limit if the dns reply multiple ips for single fqdn) and put them in the rule. 8 to 6. the second webserver is on 200. By default, the policy that the traffic goes through has whole subnet/s and debugs on that can show logs from the entire subnet. 2, traffic shaping was configured over the firewall policy. 31. This article explains how to apply traffic-shaping in a firewall policy. It can be tricky if you have other security profiles and you need to know a little about the design like the traffic flow and what zones it's hitting. set name "Fsso Policy" set uuid 1fb03232-ccaf-51e9-0a90-e44b439ef138 The prime reason here could be that the implicit deny local in policy is not created. I'm pretty sure u/pabechan is correct that this is local traffic, so your security policy won't get hit. I have created a traffic shaper with the following values: Name: 500kSharedLimit Traffic Priority: Low Max Bandwidth: 500 kbps Guaranteed Bandwidth: (not enabled) DSCP: (not enabled) I then have a Traffic Shaping Policy as follows: Source: All Check Logging Settings: Make sure that the logging settings for your policies are configured to include the Policy ID in the logs. 0/16, this policy matches when I do a policy lookup. This discrepancy occurs because the traffic loopback within the FortiGate does not allow the source IP to appear as the public IP: instead, it retains the internal IP address. When an already established IPsec VPN tunnel does not allow traffic flow, despite how no changes to the FortiGate configuration have been made since it last worked, begin troubleshooting by performing packet captures of encapsulating security payload (ESP) packets (encrypted packets) between the VPN This will log denied traffic on implicit Deny policies. 2. This article describes how to solve an issue where VIP traffic does not match a firewall policy with the destination set to 'all'. Select the policy for which you want to see the Policy ID in the logs. Follow the steps below: 1) Edit the ipv4 policy from CLI, set the FSSO to default setting. Thus, if your traffic hits policy 0, no policy matched. 1-10. Actually w hen using deep packet inspection on a FortiGate, the recommended inspection mode is "proxy You may use the debug flow commands to find out this interesting traffic is hitting which firewall policy, then double check whether the SSL Inspection profile is applied correctly or not in this policy. Regards, Vimala In this case, to do the traffic redirection, 'ICMP reply' will need to match with firewall policy and existing session since asymmetric routing is not permitted on FortiGate by default. This is a behavior by design in NGFW policy-based mode. This article describes few basic steps of troubleshooting traffic over the FortiGate firewall, and is intended as a guide to perform the basic checks on the FortiGate when a If traffic is NOT hitting your policy, than "Stop" and don't proceed until you ensure that any other network routing or filtering problems has been fixed. This prevents policy from matching. Scope FortiGate. I see traffic hitting the policy, but not returning. The traffic is still denied, still hitting implicit policy. However, there is no session established for the ICMP traffic since for ICMP requests, its source address is in the same subnet with the FortiGate interface so no policy or session is required. Enabling logging in security policies. 1 firmware. If the traffic is not hitting the Firewall, then you need to examine the routing on After changing these settings, the traffic hitting the regular firewall policy will be redirected to the transparent proxy policy. It selects the policy fine for routing but the traffic never hits the permit rule nor the remote site, the firewall rule shows a hit for traffic from the policy selected IP hitting the rule to permit the traffic outbound to the VPN interface but no traffic passes back, even though on another firewall at the branch end (the Policy from Zone (with vlan10 in it) to VPN tunnel configured, Static Route (with subnet I try to reach, and VPN interface configured) also. encrypted packets) between the - Clients/users are resolving the av update FQDN to differnt IP from what the FW is resolving the FQDN. However, the firewall policy ID 8 is showing 0 bytes. To clarify, the 'Outside_Telus' address group looks like this: As far as I know, If there is no route to the corresponding destination in the routing table, SD-WAN rules will not trigger. traffic that FSSO user traffic is blocked when &#39;Collector Agent&#39; is enabled as a user group source in the FSSO setting. Not at all, there is a default route. Fortigate 200A with version 4. 8) with 2 WAN connections (both DSL unfortunately from the same ISP) I When the Azure send ping to FortiGate then Fortigate responded and when FortiGate initiated the ping traffic Azure then its drop by Policy 0. 0/29 from PORT2. I've had a bug open with TAC regarding this in the past and they declined to fix the logging issue. Go to Policy & Objects > IPv4 Policy. x. To check the matching policy route for TCP traffic generated from source 172. When I remove the Static Route, it does no longer match (as expected). While this does greatly simplify the configuration, it is less secure. How can I set that up on a Fortigate (500E)? I am able to quarantine IP's when hitting an APP or IPS policy but just randomly trying only gets dropped. 0 (MR2 patch 2). Matching traffic is confirmed through the process outlined in this article. The route is available and the policy hit (action allow) is as expected, but no traffic leaves the FortiGate. If the traffic is not hitting the expected FQDN-based firewall policy, follow the SD-WAN rules steers traffic, but traffic must match the rule first. Guestlan is on a seperate lan. x branch, as some IKE/ESP gets logged before it gets dropped. Test case shows user RDP into window server via SSL VPN web mode successfully. The policy can be configured by going to Policy & Objects > Traffic Shaping and selecting the Traffic Shaping Policies tab. As a security measure, it is a best practice for Check Logging Settings: Make sure that the logging settings for your policies are configured to include the Policy ID in the logs. ScopeVersion: 8. One mismatch in these would explain that behavior. Ex. Solution . Note that SDWAN rules are 'policy routes', but regular policy routes have precedence over SD-WAN rules. To troubleshoot any possible issues arising by using hardware acceleration. It is possible to verify from the forward traffic logs. 0/29 via PORT1 and traffic from 172. My 40F is not logging denied traffic. To re-evaluate the traffic, the session will need to be re-established or clear There is a "policy lookup" feature on the firewall policies screen that lets you put in some details like src/dst ip and the zones and it will tell you what policy it will hit. On the other end if i set the Defualt Action to Allow and then try to block a specifi port it ignores that rule and allow all. Also run the flow debug to check why traffic is not working: diag debug reset. After updating firmware on our 600D, from 6. Configuring traffic shaping policies. And no, despite all ongoing rants about specific bugs in FortiOS 4. internet-service-name. 3[. 8 still shows the traffic going to the WAN VDOM Reply reply Check Logging Settings: Make sure that the logging settings for your policies are configured to include the Policy ID in the logs. 9: Server IP: 10. First policy matching source interface, destination interface, source address, dest. diag debug flow filter proto 1. It is important to check the default objects used in that policy have not been modified. 12. 255. We had this issue with dhcp relay, fortimanager, fortigaurd after upgrading. 1 to public IP, It is also possible to verify if there are any blocks by matching the proxy policy logs: go to GUI -> Policy & Objects -> Proxy Policy -> Select the policy intended, 'right click' and select the 'Show Matching Logs', make sure the log 'All Sessions' is enabled at least for test purpose in case the user has not enabled the option in the policy. Example local traffic log (for incoming RIP message): This article explains how editing the FSSO policy. 0 MR3 9; The difference between shaping-policy and firewall-policy implementations of traffic shapers is mentioned in the case-study below. I created a URL Category object and put just one site inside (example. In this case the tunnel interface is down so the Fortigate started blocking traffic like there was no matching policy until the tunnel interface came back up. INT - 10Gb interface with a bunch of VLANs WAN - only the Wan1 interface I see traffic hitting the policy, but not returning. 15 build1378 (GA) and they are not showing up. - Go to Policy&Objects -> Addresses and check the mac address. I 've seen now on 1-to-2 dozen occasions or more, that a firewall engineer stumbles around just to find out a inside interior firewall or router ACL was preventing the traffic destine to the identity-based firewall policies. FortiGate. In this case, the traffic shaper is defined only under the traffic shaping-policy and not defined under firewall-policy. When I set a static route for traffic to 10. 6. 8. We have 3 VDOMs. 7 (vlan_200)---- This article describes that, sometimes, the traffic is dropped by FortiGate and the debug flow shows that traffic is getting denied due to no matching firewall policy (policy id-0) although a matching firewall policy exists. Once the steps to 'enable' logging to Hard Drive have been performed the user will continue with Policy setup. Scope: FortiGate v7. . Solution: Suppose to have the below topology where it is desired to access from source to destination internally by using a VIP. Solution: After being connected to SSL VPN web mode, there is no traffic hitting the policy and it is showing 0 bytes. We can see the traffic that hit those policies. As a result, the traffic will hit the implicit deny policy. 3 and traffic is going fine. Ensure the user record is a LDAP user and not a local record. 134. Adding the source back on policy 1. It is necessary to create a policy with Action DENY, the policy action blocks communication sessions, and it is possible to optionally log the denied traffic. 0 (MR2 Patch 2) and . As the traffic remains within the FortiGate and does not exit due to the hairpinning, the source IP would be an internal IP rather than the public IP. The FortiADC blocks all traffic. Related Fortinet Public company Business Business, Economics, and Finance forward Step 3: FortiGate Configuration Configure Interfaces and Policies on FortiGate: Ensure that the FortiGate has interfaces or sub-interfaces (if using multiple VNets) corresponding to each VNet. Solution Topology: User Machine &lt;--------&gt; FW &lt;-------&gt; Internet Tested IPs in LAB on version 7. Here is the details: CMB-FL01 # show full-configuration log memory filter config log memory filter set severity warning set forward-traffic enable set local User does not match User Host Profile requiring LDAP Group.

FortiGate Solution. Solution - Make sure to enter the right mac address. address, service and schedule is followed, all policies below are skipped. The destination ips are NATed, so I need to know, Traffic shaping policy 10; FortiAP profile 10; Intrusion prevention 10; 4. One of the possible reason is that the fetched FSSO groups on FortiGate have been enabled directly on the firewall policy. There was "Log Allowed Traffic" box checked on few Firewall Policy's. Note that in the output in bold above, the FortiGate provides more information about the policy matching process and along with the "Allowed by Policy-XX" output, provides a means for confirming which policies were checked against the corresponding traffic based on matching criteria and which policy was the best match and ended up allowing or denying the traffic. 4. Interestingly enough, in "Log & Report > Forward Traffic" there are no hits for policy 4. [ul] I have a Fortigate 50E (6. Then it should be put in Quarantine for 1 hour. - policies are checked from top to bottom. 1) Create a new policy and place it at top This article aids in troubleshooting network connectivity via IPSEC VPN. In lieu of manual local-in policies where the feature has been enabled and policies defined, local-in policies are built dynamically from the configuration of upstream services ie management interface config, service config etc. You should be able to see some difference in the traffic that is hitting them. This article describes the situation when traffic is not matching the policy filtered with the source mac address. (It is possible to capture the packet capture with memory for lower amounts of traffic. If there is no user-defined local policy applying to the logged traffic, logs will instead show policy ID 0. In this case, policy ID 0 is NOT the same as implicit deny. 0/24 range. the best practices for firewall policy configuration on FortiGate. 222. # config firewall policy. Filter the forward traffic log with policy ID. In this scenario the site to site VPN between two FortiGates and the tunnel status is up however, both local and remote subnets are not able to reach each other or only one way communication is working. SolutionVerify the following:1. 8 still shows the traffic going to the WAN VDOM Interestingly enough, in "Log & Report > Forward Traffic" there are no hits for policy 4. 200. 10. I am guessing you have 2 routes in the routing table with same distance. Solution Users may face an issue while accessing the internet when there is an outgoing interface as an SD-WAN with more than one WAN interface, such as W I don't see a reason why we have to use policy route. # diagnose sniffer packet any 'host <VirtualIP>' 4 . See link below. Traffic will not be re-evaluated anymore. Via the CLI - log severity level set to Warning Local logging . We just replaced an ASA with a Fortigate 100f. The firewall session shows it is hitting policy 0 for the RDP connection traffic: When a FQDN-based destination address object in firewall policies is used, whenever incoming traffic coming from LAN to WAN, it should hit the configured firewall policy with the FQDN destination object, if all the other required fields match the firewall policy. In most cases, it is recommended to select security events, as all sessions requires more system resources and storage space. Any supported version of FortiGate. I've checked the "log violation traffic" on the implicit deny policy in both the GUI and CLI and it is on (which I believe should be the default anyway). It is possible to see all of the traffic logs of the PC. Solution Avoid enabling the fetched FSSO g Description This article explains about reply traffic which is not matching any of the configured policy routes or SD-WAN rules. Scope: FortiGate. 0MR2 9; FortiGate v4. Wan adresses are 200. 3. The article sometimes simply refers to SD-WAN rules as 'rules'. 64.

I'm trying to get policy routing working in which case traffic from one device will always use a specific wan circuit while all other traffic uses the other wan circuit but it doesn't seem to work. As @jiahoong112 mentioned please verify the configuration of your Virtual IP first and if everything is fine there, you can run a diagnose sniffer command to see if the traffic matching the VIP is entering the firewall or not. In some environments, enabling logging on the implicit deny policy which will generate a large volume of logs. 2 255. 135. This article describes how to troubleshoot issues where traffic does not match any policy although the policy is already created. Sol To allow CLI commands such as the packet sniffer and debug flow to display all traffic matching the policy since traffic offloaded by SPU hardware on a FortiGate device is not visible by those CLI tools. I have set up ssl inspection, web filter, ips and antivirus about 2 years You may use the debug flow commands to find out this interesting traffic is hitting which firewall policy, then double check whether the SSL Inspection profile is applied correctly or not in this policy This document explains how to enable logging of these types of traffic to an internal FortiGate hard drive. There should be a firewall-policy Hi @nsharpley . Lets assume there is a WAD debug to be run on a particular source ip/policy. set intf "port4" Hi, PanOS 9. Solution.
