Hello All,
I have an issue where I have a router with 2 Wan exit points. I have setup IPSLA to roll from a 3G connection to a Vsat connection if the 3G internet path is unavailable. All looks ok and I get reliable route updates in the route table for the failover. My issue is that the Nat overload route map is not operating correctly. When I roll from 3G to Vsat traffic flows ok. When the 3G come back online the route is re-entred into the route table but I get no traffic throughput. When I remove the Vsat Overload statement the traffic flows back out the 3G. Am I missing something? Any advise much appreciated
