Virtual -Access Interface drops after VPN peer change
I have a Cisco 837 ADSL out in the field. I am migrating it to a new VPN concentrator. The VPN comes up fine and the network is reachable, for about 7 minutes, then the line protocol on the Virtual-Access interface changes to down and the dialer looses its public IP address. If I reload to the old configuration with the old peer, the Dialer gets its public IP back and everything works fine. Is there something anyone can think of that would cause the public IP address to be lost after changing VPN peer? It's wierd because the new VPN comes up and everything works fine for a few minutes before completely breaking because the dialer looses its public IP:
