I have 3mg DSL running client 4.06. I have a very reliable and consistent 2.6mg actual bandwidth. My VPN account is set to terminate after 4 hours of inactivity. The tunnel drops at 5-8 minutes. If I start a continuous ping to an ip on the same LAN as the concentrator, the tunnel will never drop. If I open a file share with a server on the same LAN, it increases the tunnel connection time to 30-40 minutes but eventually drops. Any ideas?
