I have a Linksys RV082 with a dual-WAN setup, connecting back to an ASA 5510 via VPN. The Linksys VPN configuration connects to the ASA on the WAN1 port primarily, and has the backup tunnel defined as connecting to the ASA via the WAN2 port. The ASA is configured to accept connections from both IP's. This all works- should the primary connection go do, the Linksys notices this fact and re-connects the tunnel on the secondary port. However, I can't figure out how to get the routing rules (IPSec Rules) on the ASA to follow suit.
I have both the Primary and Secondary ports defined in the IPSec Rule table, with the primary connection having a "lower" priority number than the secondary. However, when the primary tunnel fails and the secondary connects (which it does successfully), the ASA continues to try to send traffic destined for the remote subnet over the primary tunnel. This, of course, fails miserably, as the primary tunnel is no longer up, but the ASA never tries the secondary route. How can I configure this such that should the primary port on the linksys go down, it can not only re-connect the tunnel on the secondary port, but also have the ASA pass traffic over said tunnel? Thanks.
