Cisco 1841 Advance Security Image - OER Border router connected to business-class DSL
Cisco 2811 Enterprice Image - OER Master/Border connected to T1
Cisco 3750 Layer 3 IP Base image - Default Gateway to clients
Issue: OER is functioning well and the prefixes appear to be working correctly for traffic initated by the clinet (generic web browsing). However, traffic such as VPN and SMTP that is initiated from the Internet is sometimes load balanced to the other border router, which kills the connection to the remote client. The remote clients are dynamic IP from users working from home, so there is no way that I can find to do a static prefix map. I have looked for weeks for a way to force traffic flows to go through the router it was initiated through for SMTP and VPN, but no luck. Anybody have an idea?
Thanks in advance.
