Cisco 871 Router VPN tunnel Dropping after 60 seconds

By millss ·
I am having a problem using EasyVPN on 871 routers for telecommuters. Everything works great as far as authentication and access. The problem is that after 60 seconds the VPN tunnel will drop and you have to open the Web browser authentication window again before it will re-establish the tunnel. The tunnel is being established to a 3000 series Cisco VPN concentrator and I have the timeout set to 300 minutes on the group setting.
When the tunnel drops I see a "Disconnect requested by remote end" in the VPN logs for the concentrator. I am at my wits end trying to figure this one out, if anyone can help please let me know.

This is assuming you're using GRE or IPSec Tunnel, or, both:

Try adding the following syntax in your
crypto isakmp policy 1
crypto isakmp keepalive 10

Also, try adding the following within your Int Tunnel
keepalive 10 3
