FortiGate Solution. 2. diag debug flow filter proto 1. ScopeVersion: 8. Case 1: When only a traffic shaping-policy is used. Below are the steps to match the source-ip to a policy to analyze further for that source host. Solution: Occasionally when creating a firewall policy from 'WAN' to 'LAN' with the destination set to 'all', VIP traffic is not filtered by the policy. INT - 10Gb interface with a bunch of VLANs WAN - only the Wan1 interface I see traffic hitting the policy, but not returning. 2, traffic shaping was configured over the firewall policy. 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. Solution There are three attributes that can be configured in the SD-WAN service with ISDB: internet-service-custom. However, it is visible from a debug flow that the traffic is matching the implicit deny. 2 and above local traffic sent from the fortigate does not follow sdwan rules. Solution - Make sure to enter the right mac address. 12. 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. Lets assume there is a WAD debug to be run on a particular source ip/policy. 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. Now, I have enabled on all policy's. 1 firmware. Interestingly enough, in "Log & Report > Forward Traffic" there are no hits for policy 4. 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. By default, FortiGate will not generate the logs for denied traffic in order to optimize logging resource usage. - policies are checked from top to bottom. If there is no user-defined local policy applying to the logged traffic, logs will instead show policy ID 0. 254 If server2 traffic is hitting policy 15 then policy 20 isn' t catching it. S II. The route is available and the policy hit (action allow) is as expected, but no traffic leaves the FortiGate. Matching traffic is confirmed through the process outlined in this article. x branch, as some IKE/ESP gets logged before it gets dropped. 2 255. 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. FortiGate was considering the destination IP for return traffic as its own IP and not forwarding the traffic via the correct interface. 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. This is a behavior by design in NGFW policy-based mode. Scope . 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. 3, I do trust my Fortigate 100% that firewalling still works! Right, made those changes, but the traffic still does not pass. Solution Configuring the FortiGate with an ‘allow all’ traffic policy is very undesirable. set intf "port4" Hi, PanOS 9. 10. Scope: FortiGate. 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.

Solution The traffic being denied by policy 0 since captive portal was enabled on interface level. 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. In some environments, enabling logging on the implicit deny policy which will generate a large volume of logs. x. 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. 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. From the internet this website is accessable. You can check only 3 parameters: source IP, destination IP and service. diag debug enable. While this does greatly simplify the configuration, it is less secure. By default, if the intention was to apply Hi! I am having a very weird setup for our Fortinet Stack. 9: Server IP: 10. One of the possible reason is that the fetched FSSO groups on FortiGate have been enabled directly on the firewall policy. 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. If it doesn't hit any it is likely a route missing or confused. We can see the traffic that hit those policies.
