For a failover configuration i would like the network autodiscovery function of the VPN concentrator (lan-to-lan), which uses rip via the ipsec tunnel (my assumption).
at the other end is a pix fw terminating the tunnel. is there a way to get the pix communicating via rip with the vpn concentrator safely over a wan link ?
vpn ---- router -------wan----- router-----pix
|---------------ipsec-tunnel---------------|
your help is appreciated.
