I've tried allowing worldserver.exe, Authserver.exe and MySQL.exe tunneling access (VPN disabled for these files) but the license fails. If I exit my VPN everything works fine. I tried searching for VPN in the search field on the forums and received zero hits. Is there something else I have to give tunnelling permissions to run? I should add that I mess around with the repacks as a single player, so there's zero need to allow network access to the server for other players.
