NAT'ing Multiple WIC's on a 2811 router

I am trying to set up 2 outside interfaces on my router so that I can route a specific traffic thru one ISP, and all the other traffic thru another ISP. The first WAN interface is the normal FE0/1, but the second WAN interface is a 4 port EtherSitch High speed card (HWIC). Since I can't set a public IP on the individual ports of this HWIC, I have to assign it to the VLAN that hosts these 4 ports. My question is this...How do I NAT this VLAN as an outside interface when I'm already using FE0/1 as the defualt route? Or, is this even possible. I have 1 LAN port that I'm looking to route normal Internet traffic thru FE0/1, and route the traffic to our imaging server in Houston thru the VLAN, which I've set up as the outside interface. Is this even possible?

Hi

You could try with policy routing. Assuming your default-route will push traffic out the fe0/1 interface

imaging server = 192.168.5.10

vlan interface = 10

access-list 101 permit ip any host 192.168.5.10

route-map PNAT permit 10

match ip address 101

set interface vlan10

Then configure "ip nat outside" on both the fe0/1 and the vlan 10 interface.
