I just stood up an XG210, I have a remote access SSL VPN set up but some of my client machines crash when connecting. We get this bluescreen:
All the affected computers are Dell laptops running Windows 7 Pro. Crashes happen with both the Sophos client downloaded from the user portal and OpenVPN 2.4.3-I601. I updated Windows and all drivers. This isn't happening on all my clients, and I don't see any hardware or software differences between machines that crash and those that don't.
I tried a few things, safe mode, then clean boot - adding services one at a time. The OpenVPN Interactive Service is the one that corresponds to the crash. Running the client without that service running appears to connect, gets an IP, but I can't access the network I'm connecting to.
So I looked into that service; my understanding is that lets the client do some things that require it to run as admin without running as admin. I tried running the OpenVPN client as an admin with the service disabled - crash.
Looking at the logs, there were a few ROUTE ADD commands, that fail when the service is not running. I tried entering them manually, it crashes shortly after entering
route add 0.0.0.0 mask 128.0.0.0 10.81.234.5 (when the VPN has the 'use as default gateway' checked)
or route add <internal IP> mask 255.255.255.0 10.81.234.5 (when default gateway not checked)
it looks like adding a route that already exists might be the issue? I don't understand why it works on some computers and not others.
I would sure appreciate any thoughts anyone has on this.
