HF - Multiplayer via IPX

[Burn.E]

Hi Guys,

perhaps somebody can help solving my problem with Hellfire multiplayer...
I wanted to switch some "uniques" to a mule-char via an IPX-game.
Therefore I've connected two PCs with a crossover-cable.
I've installed the same versions and patches/updates on both PCs
- HF V1.01
- hellfui.dll
- command.txt
The multiplayergames are displayed, but I can't join them.
Error: "Unable to join gamename" or "Unable to join game gamename"

1 PC - WinXP with installed IPX protocol - Firewall deactivated
2 PC - Win98 with installed IPX protocol - No firewall installed

Thanks for all hints
