Hi Guys!

I want to seek advice on how to deploy a Firewall Appliance side-by-side with a cisco router. The topology is like this. Cisco Router -> Firewall Appliance -> VLAN SW.

I have already created a transit link between the units. The firewall appliance can see the router interface but the cisco router received reply time out from the appliance.

Thanks in advance!

how are you testing this? You do know if you are pinging the interface, the firewall will drop the packets....

We would need lots more information.
