I meet a problem that the vpn client keeps disconnectiong and need to reauthenticate. Sometimes it disconnected after the vpn client is connect to ASA for 5 minutes, sometimes it's 20 minutes. But the worst thing is, even the client is using the tunnel, it disconnected.. With continus ping, it disconnected.
In the group policy, the vpn-idle-timeout is set to 45. And isakmp keepalive threhold is 300s. Does anybody aware of this problem?
Any suggestion are appreciate.
