Router has three interfaces.

I have two interfaces connected to our extended WAN network. When one link fails I want NAT to remain active for our LAN network. WAN interfaces use OSPF. Is it possible to issue the "ip nat outside" command for both "WAN" interfaces? Is there another way to do this that would work better?


I have this problem too.

Hi Dan

Can you post a topological diagram which can explain the setup in brief..

hi there,

There could be a solution to your query but what i undestand from your network diagram is that u want to use wan 1 as primary and wan 2 as secondary .

so simply go with the static routing with higher and lower metric.

if you want to use the ospf on your interface just redistribute the static route in ospf.

hope this will help.

Yes, wan 1 is primary wan 2 is secondary.

I will be using ospf to redistribute the routes.

My real question is, will the NAT work correctly, specifing "ip nat outside" on both WAN interfaces?
