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
