Hellfire seems to have Bnet support but it's disabled I think. I tried getting it to connect to my PvPGN server but the way it starts a connection is quite unusual and is unsupported. It sends an undocumented UDP packet of 1 byte to begin with.
Is anyone willing to help out?

Actually you would have to patch it to the current storm.Dll found in the d1 game from patch 1.07 i think, which hasn't been supported since they updated to 1.08, currently Bnet only supports the DLL files from 1.09a/1.09b
