[DFLW] Yet more Multiplayer issues

[Admiral Barrett]

While I have prefixed this as a Land Warrior thread, it also applies to Task Force Dagger, as well. When starting LAN sessions, the game hangs at "Analyzing Mission Topography." However, unlike all of the threads I have read about how uncooperative the game's netcode is, the issue appears for most, but not all of the maps. For example, In Land Warrior, I can start a Deathmatch session on the Oil Rig map with only about 20 seconds between the hang and the other players joining. In Task Force Dagger, the Carnage Bridge map also works, but it takes the server ~ one minute to let other players in. For the rest of the maps and other game types, the game hangs at the aforementioned point.

1)I have opened ports 17478, 3568 and 3569 on my router.
2)I have both entered a Windows Firewall exception AND disabled the firewall.
3)I have the GOG version of the game, where the NoVON patch is already applied; even so, I have tried the NoVON patch and it does not resolve the issue.
4) I have no issues with either DF1 or DF2; multiplayer works like a champ on all maps.
5) All of the games use IPXWrapper's latest release to tunnel through the network.
6)Operating system seems to be irrelevant. I have XP SP3, Vista 32Bit and Win7 64 Bit. Same issue with no deviation.

I am at a loss as to why only a handful of maps in Land Warrior and Task Force Dagger will actually work. I do not know where to look to debug at this point. Unless there is an obscure port that is still blocked, my only thought would be an issue in the multiplayer map settings themselves. What do I need to do to get this fixed?
