We have a Cisco ASA 5505 on a new Comcast line that three other 5505's connect to via Easy VPN. When this line gets flakey, it looks like the easy VPN connections stop sending data and the users cannot access anything over that VPN. When I go to Monitoring > VPN statistics > sessions it shows that the Tx and Rx bytes are at 0. If I click "Logout" to force the easy vpn connection to reconnect, the connection will come back and stay at 0 bytes. This problem never occured on the old DSL line that never went down. What do I need to do to make these VPN connections reliable even if the line goes down and comes back up?
