Hi,

In our new network setup we have two Router 3600 connected to the two different sites with two links that is

S0/1

Site A S0/0 ------R1------------------SiteB

S0/0---------------R2 --------S0/1

for the two site we have two fiber connectivty

now the issue is we need to do NAT for both the sites for IP nat inside i can give for IP nat outside whether i need to give it two Serial interface

is it possible to IP NAT outside to S0/0 and S0/1

and also suggest me best way to make redunancy

Thanks
