Actually our problem is the one application which base on telnet keep dropping out every 15 minutes in IPSec VPN environment (ASA to router). So I am checking if I can set the TCP connection time out in a longer value on router and ASA to resolve the issue.
I checked the ASA, the VPN tunnel has been up and running for more than 24 hours, so I don't believe it's tunnel up/down issue. Also all other applications are working fine except this telnet applications.
And the issue didn't happen when we used frame-relay circuit before, we just migrated to DSL VPN in last week. I added the CBWFQ on ASA and router, but it doesn't help.
