Policy Routing Question

Hi All,

Do you have any way to know if a policy route (PBR) is being used? Something like a hitcount ...or some counter that tells me when it was last used?
Regards!

Hi,
As per my knowledge, there is no such way but you can use the sniffer trace for a real-time trace to any packet. You will get an idea.

My problem is that I have a legacy firewall with many PBRs. I wanted to disable them. Using the sniffer can take a long time to validate all the PBRs. So I thought I could have some statistical indicator of use of these PBRs.
Anyway, thanks for the help.
Regards!

Thinking outside the box. What if you made sure the policy bases routes would use a rule if hit. You could then use the rule counters. For example if a policy based rule applied to 192.168.5.5 to 8.8.8.8 you make a rule to apply only to that traffic.

You can verify and confirm by checking the routing table and debug.

FGT # get router info routing-table all
You can see the routes added for you policy route.

FGT # diagnose sniffer packet any "host <ip address>" 4
or is services are involved the you can use
FGT # diagnose sniffer packet any "host 10.160.0.10 or port 80 or port 53" 4
