C2811 Separate Ingress / Egress Interfaces (Satellite Modems)

I have a 2811 Router with two fast ethernet wic cards installed. I need traffic to go out one interface, but it's received back through another. Both interfaces have public IP's and the same subnet, and are connected directly to satellite modems. One can receive data / the other only send.

What is the best way of accomplishing this?

I believe the transmit-interface command takes care of this.  It's under the interface sub-menu.

Thanks!

Do you have an example of the configuration that you could share?

I have int fa0/0 setup as an inside interface with a DHCP pool.

Int fa0/0/0 is the egress interface with no IP address, int fa0/1/0 is the ingress with a public IP and transmit-interface as fa0/0/0.

The default route is 0.0.0.0 0.0.0.0 (transmit modem public ip)

Is there any additional config I require to send / receive data via separate interfaces?

Sorry, I do not have a sample config but I did find this.  https://supportforums.cisco.com/thread/30956  I would almost think you would need a 3rd ethernet interface.
