My scenario is this

I have a cisco 1941 router base with an additional card slotted for 1 extra Ethernet port.

I need to put a tunnel on 1 port to a remote site for file server access on a low bandwidth Ethernet connection.
Then i need to route all non tunnel traffic over the additional slotted Ethernet card High band width connection.

I been looking at configs that i think should work but it seems I am missing something. As i cant get the nat translation to match anything other than the Tunnel outside ip address. Any advice would be appreciated.. I am sure i am missing some thing simple. Here is config example...


crypto map match IPSEC traffic

interface GigabitEthernet0/2
description LAN connection
ip address 192.16.42.1 255.255.255.0
ip nat inside
