Sonicwall SSL VPN users sometimes experience frequently lost connections
Posted on 2010-09-02
We have a Sonicwall SSL-VPN 2000 running version SonicOS SSL-VPN 220.127.116.11-16sv that serves typically four to six people at once. Occassionally, I get a call saying that the user is in a connect/disconnect loop with the device. I see nothing unsual about the device, other users might be connected persistenly at the same time.
It happens enough that I wonder if something is configured wrong on the systems side. I cannot find much on the knowledgebase or from tech support, or from Google on such an issue. Thought I would try this forum for suggestions or advice. The users are connecting the netextender client on Vista.
There are some properties settings such enable/disable use TCPv6 that I wonder if anyone has experimented with. I have also started asking users to enable and send their debug log.--I can't see much in the system debug log.
