Possible to NAT with failover interface?

Tommy Svensson

Level 1

Hi.

I have managed to get a failover to work on my Cisco 1941 router. If one interface drops the other one pops up and enables a route for the traffic. How do i do about the NAT configuration in this case?

For testing i have my primary interface on IP 192.168.96.20 and my secondary interface on 192.168.97.20. I want the secondary interface to take care of NAT when the primary goes down. is this possible ?

And if i have a default route like this 0.0.0.0 0.0.0.0 gig0/0

gigabitethernet 0/0 being my primary interface.

What happens to that route if the interface goes down? Can i add a second default route it that happens?

Regards Tommy Svensson
