I am looking for examples or assistance on a Cisco 1811 please with static NATs.
I have three ISPs (T1, DSl1, and DSL2) and several statically NATted Web servers, and mail servers (each with a unique IP address). The problem is that traffic comes in on the link from the T1, for example, and can go back out on any of the three links. I want to reverse map the outbound traffic so that it goes back out on the same link *and address* it came in on since there are several virtual IP addresses involved.
I am not sure route maps will work since the do not specify the source address used in the return packet, or can they?
Any ideas? thanks!
