I am a relatively beginner Networking Guy and I have managed to set up a Cisco 2911 router with two ISPs (no BGP), NAT and route-maps (although I don't really understand them) to the two up links with one default route and another floating static route.
My question is this: Since only one uplink is active at a time, I am not able to receive incoming connections from the redundant link as on the way back they are router through the default route (not the floating one which they came in from).
Is there any way I can have data incoming from the redundant link, go back through the redundant link? I would appreciate if you can also supply some example commands with your response.
For reference, here are some excerpts of my configuration:
