We have a 2801 with two ISP connections. NAT is configured and all seems to work well, but we have noticed on occassion that if inbound traffic is coming in on one link (to Fa0/0 for example), the return traffic is being sent out the other link (Fa0/1) as this does have a default static route pointing to it. We need to ensure that traffic is sent out the correct interface without changing the statics. We have looked at OER but could not make it work.
Attached is a copy of the config, showing the relevant sections, with IP addresses hidden (all the <xx> entries).
Has anybody experienced the same issue, or have any suggestions? This should be straight-forward, but we are just coming up with blanks :(
Many thanks in advance
