VPN client get disconnected

Unanswered Question
Sep 2nd, 2009

we have ASA 5520, and all our clients use login via VPN client with IPSEC. However, users are complaining they are getting disconnected intermittently. Is there any limit for users connecting via IPSEC? Any help towards resolving this issue will be much aprpeciated.

I have this problem too.

Anand asks if there are limits on the number of IPSec VPNs and the answer is yes there are limits. The limit varies by platform and license. The output of show version should indicate what the limit is on that ASA.

There are several things that are more likely to cause the disconnects than the limit on IPSec VPNs. You should consider the possibility that the ASA is terminating sessions because of an inactivity timeout, or terminating because of a session time limit, or terminating because there was some (fairly short) interuption of traffic going through the Internet.

Thanks for your response. I checked the configuration and these options are already in there, so far from last two days I have not heard any disconnect issues,however some remote tech support users who do VPN to access servers via VNC claim it is really slow and takes long time. Is there anything to check in ASA or any other ideas. Please reply.

Still the vpn connection is getting disconnected. Is there anything to be checked in the VPN config.
