2 LANs are not reachable to eachother

[majidsolehri]

In Palo Alto Firewall, we are facing an issue. we have configured 2 LANs and 2 WANs. working fine even load balancing also works.
But LANs cannot ping/reachable with eachother. even both lans having internet access.
How can we configured that LAN can reachable with eachother and rest of configuration remain same.

Thanks

did you use 1 single virtual router for all 4 networks?

in that case all you need to do is create a rule that allows traffic from one lan to the other, and a rule in the opposite direction

both for the app-id 'ping'

if you used 2 separate Virtual Routers, you will need to create routes for the 'distant' network (i.e. on VR1, create a route for LAN2, next hop VR2. on VR2 create a route for LAN1 next hop VR1)

We are using single virtual Router also add policy on top LAN1 to LAN2 and vice versa but still both LANs are not reachable.

What have you seen when reviewing the traffic logs? How did you structure the allow policy?
