We have this route-based VPN with partner. It is static routing with VPN site A as preferred.
Problem that sometimes partner, which is normally on-site A, becomes Active on B site, while our route is still points to A. We see traffic all looks good, just the thing that we send traffic to site A and get it back through site B. Looking at the logs i don't see drops, but users say they have no connection. Spoofing is not an issue, so not sure what exactly kills the connection. I assume Asymmetric routing is to blame one way or another.
>Is there any way to live with Asymmetric routing situation in Route Based VPN?
(At the moment i have only static routing at my disposal, as have some corporate limitations on running dynamic routing on the firewalls.)
