VPN client works on my laptop and desktop and both are running Windows 8.1 Enterprise.
How is your SSL VPN setup? What do you have added for the Local Networks? I know where I work one of my co-workers just created a network object for 10.0.0.0/8 and that broadcasted that route when you VPN'd in. Well, that wasn't a good idea so I created objects for each network and then created a Network Group and added that to the Local Networks.
Once that was added, you could see all the correct routes when doing a route print.
Not everyone--we have users here that use the product at home, and there is a home user license for that, and VPN is enabled in that license; however, official support is not provided for the home user license.
Hey Martin, thanks for the update... I'm sure that Sophos will be updating their SSL VPN Client in the next firmware update or two now that OpenVPN has fixed the tap driver.
