We have an new ASA 5510 configured for IPSEC remote VPN connections. Everything is working well except that telnet sessions to a business system at headquarters timeout while idle. It appears that they time out after about 2 hours. Our idle timeout is set to 4 hours in the group policy for IPSEC users. I don't see any other idle timeout setting that could possibly apply to this issue. Anyone have any ideas on what could be causing this?
