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. Now, I am able to see live Traffic logs in FAZ, ok. ) Send the traffic to the non-functioning app or website. 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. 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. 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. I am guessing you have 2 routes in the routing table with same distance. By default, if the intention was to apply Hi! I am having a very weird setup for our Fortinet Stack. 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). 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. 168. 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. One mismatch in these would explain that behavior. encrypted packets) between the - Clients/users are resolving the av update FQDN to differnt IP from what the FW is resolving the FQDN. This is a behavior by design in NGFW policy-based mode. 0. The following policy should allow all traffic from the 100.
