Hello,
I run into issues with a "simple" policy.
Here some screenshots to explain the problem.
One policy 16 that allows all from "dial-up" to "root-vpn0". Counters going up:
Policy lookup failed for one I am sure that one should match the above one ID 16:
A route lookup that looks good to me:
Hitting 0.0.0.0/0:
Even "diagnose debug flow" looks good:
But no page displayed on the browser on client ip-address: 10.64.1.2
Did troubleshooting with an extra switch, new extra VDOM, factory-reset restore config, but no succes.
Does anyone can give me a hint to look for?
Kind regards,
Philip

Hello Philip,
Check if the policy is enabled and in the right sequence: Ensure that the policy is enabled and in the right sequence to be matched. The policy sequence can be checked in the policy section of the GUI.
Clear the cache: Clear the cache in your web browser and refresh the page. This will ensure that the page is loaded with the latest information from the FortiGate unit.
Try a different browser: Try accessing the FortiGate GUI from a different browser. If the issue persists, try accessing it from a different machine.

Hi,
Can you post the output for:
get router info routing-table details IP , for both IPs?
Here the requested info:
FG100D-D (root) # get router info routing-table details 10.63.1.3
Routing table for VRF=0
Routing entry for 10.63.1.0/24
Known via "ospf", distance 110, metric 11, best
Last update 00:11:34 ago
* 10.77.1.5, via dial-up_0
FG100D-D (root) # get router info routing-table details 171.22.67.34
Routing table for VRF=0
Routing entry for 0.0.0.0/0

Very strange. Maybe it's just a visual thing in the GUI ?
Does a policy lookup from the CLI say that it doesnt match any rule ?
diag firewall iprope lookup <src_ip> <src_port> <dst_ip> <dst_port> <protocol> <Source interface>
If I understand correctly the traffic is working as expected as for the debug flow ?
The "diagnose debug flow" gives an "Allowed by Policy-16", the correct policy.
Here the output of 2 times the diagnose firewall iprope lookup:
FG100D-D (root) # diagnose firewall iprope lookup 10.63.1.3 61628 171.22.67.34 443 6 dial-up
<src [10.63.1.3-61628] dst [171.22.67.34-443] proto 6 dev dial-up> doesn't match any policy.
Command fail. Return code -49
FG100D-D (root) # diagnose firewall iprope lookup 10.63.1.3 0 171.22.67.34 443 6 dial-up
<src [10.63.1.3-0] dst [171.22.67.34-443] proto 6 dev dial-up> doesn't match any policy.
Command fail. Return code -49
Maybe you need dial-up_0 ?
That one looks better:
FG100D-D (root) # diagnose firewall iprope lookup 10.63.1.3 0 171.22.67.34 443 6 dial-up_0
<src [10.63.1.3-0] dst [171.22.67.34-443] proto 6 dev dial-up_0> matches policy id: 16
I'll check the OSPF config.
Found the problem. An upstream FortiGate had a static route.
Troubleshooting this issue, I used "Policy Lookup" on a downstream FortiGate, the FortiGate where I worked on. This one finally didn't had an issue.
But, why didn't the Policy Lookup work. Here my troubleshooting steps.
The command: diag firewall iprope lookup <src_ip> <src_port> <dst_ip> <dst_port> <protocol> <Source interface>
This one helped me.
Here a policy match for 1 lan interface and 2 dial-up interfaces. Notice the "dial-up_1" and "dial-up_0":
In the Monitor => IPsec Monitor section, there are 2 tunnels, dial-up_0 and dial-up_1:
The policies 22, 23 and 25, see above diagnose screenshot, have counters increasing:
But the Policy Lookup:
just doesn't show up interfaces dial-up_0 and dial-up_1, instead of the lan interfaces which is shown.
The CLI diag firewall iprope lookup works, the GUI simply does not for dial-up interfaces.
Above troubleshooting was on:
FortiGate 100D
v6.2.13 build1343 (GA)
