ADSL VPN Problem: 2621 > VPN3000 Concentrator

Can anyone help me.

I've configured a Cisco 2621 with a WIC-ADSL1 card to create a VPN back to my main site. The VPN comes up and encrypts the data fine. However, the line seems to randomly disconnect. It comes back when I remote the crypto map commands from the dialer and reinstate them??! Very strange. Can someone take a look at my config and see if they can spot the problem?

Obviously I've changed the IP addresses in this config. However, the psuedo addresses are in the correct places.

Probably a phase 1 timeout issue. The 300 series concentrator hsa the live event log feature that give pretty good info. The router defaults to a lifetime of 84600 seconds. Check to see what it is set for on the concentrator.


It is what it is!!
