I have an ASL v4 as a VPN Gateway with High Availability. It's protecting just an internal network from an external network (roadwarrior connections) and I have a NAT box for the external connections - it works fine with nat-traversal (draft-00).
When I disconnect the internal interface, the ASL slave becomes active and the VPN connections renegotiate the tunnel, everything is ok. But when I disconnect the external interface, although the ASL slave becomes active, the VPN connections don't try to renegotiate the tunnel again.
I am using network cards that support link beat, so I am a little bit confused with this situation, could you give me some ideas. Thanks in advance.
