Starcraft over PPTP VPN connection.

Has anyone ever got Starcraft to do a LAN game (UDP) over the WAN using a PPTP service like PoPToP?  I heard it's one of the few VPN daemons that supports broadcast packet relay, but even after getting it completely set up my VPN clients cannot see games that I host.

Just tonight I tried Hamachi by itself, didn't work.  But when I used BattleLan over Hamachi, that worked.  SO WHAT THE FUCK?

How do YOU go about playing SC off of bnet?
