Watchguard SSL VPN client on OSX 10.7 Lion TUN/TAP Kernel Problem

I upgraded to OSX 10.7 Lion and lost the use of the Watchguard VPN client.

I eventually found a solution at http://lesmond.net/2011/07/watchguard-ssl-vpn-client-on-osx-10-7-lion/

I had already uninstalled Watchguard VPN and tried to reinstall to see if that worked (poor advice from another forum)

I hadn't manually removed Watchguard icon from the dock.

When you try to reinstall the dialog tells you to run an postupgrade script on the TUN/TAP kernel and then quits with a fail.

If you install openVPN in this scenario you get an openVPN app and menu item, both of which do nothing.

Click on the Watchguard dock icon and connect.

I was then asked to upgrade and ended up with the run post upgrade script dialog and quit with a fail.

I then clicked on the Watchguard doc icon again and connected.

This time it connected with no problem.

Hope this helps!
