Thanks OP, was really looking forward to a Beta Private Server
One thing though, I configured everything, no errors what so ever, just... when I try to log in with the account I made, it gets stuck on "Connected" for a split second then it says "Unable to connect". I also tried closing mangosd.exe and realmd.exe and ran WoW again, got the same issue.
Seems like the game/server/whatever fails to see that mangosd and realmd are running...
How can I fix this, any ideas?
