I'm using a Sonicwall TZ 170 and I'm attempting to VPN into our network from a remote site (ex: a coffee shop). I open Sonicwall Global VPN Client, click enable. It prompts that I have been connect successfully. Then I attempt to connect to our server, for anywhere from 10 seconds to 2 minutes it works perfectly! Then nothing works. I can't even ping our server or any other workstations. I've check the log of the client, windows logs, and the log on the Sonicwall and there are no errors.
I've looked through the Sonicwall getting started guide and manual; it appears everything is configured correctly.
I ran a test to try to see if the disconnection was a timed occurrence and it doesn't appear to be. I timed from the moment that I was prompted that the VPN connection was established until I was no longer able to ping the server. These are the timespans (mm:ss).
With no errors, I'm clueless on where to look next.
Thanks in advance.
