BAT Mod LAN support difficulties

I installed the BAT Mod version 3.19 from here:
http://civ4bug.sourceforge.net/BATMod.html
with instructions from here: http://sourceforge.net/apps/mediawiki/civ4bug/index.php?title=How_to_Install_the_BUG_Mod

It works well in single player mode (with a few bugs, like starting on the water once, but, that is another post).
However, I am trying to use it with another computer via a LAN (router), that also, installed the same version from the same site with the same method.
Both computers have BTS v3.19 installed.
Both computers will run BTS v3.19 in single player mode.
Both computers will run BTS v3.19 in multiplayer over the LAN, before and after the BAT Mod installation.
Both computers will run BTS v3.19 with BAT installed in single player mode.
(I have seperate Icons for running BTS, and BTS with BAT Mod).
Both computers will run BTS v3.19 with BAT installed in multiplayer mode up including the point of creating the new game, however...

Neither computer will permit the other computer to see the new game created, so, the 2nd computer can't login to the game.

I checked the FAQ: http://sourceforge.net/apps/mediawiki/civ4bug/index.php?title=FAQ#Common_Issues
They reference multiplayer over the internet, but, not via a LAN.
It refers to the opening of certain ports for internet use.
Which should not be the issue here.
I have not needed to open ports for LAN use on BTS v3.19, that I can remember.
If any were opened when the game was installed, wouldn't BAT use the same ports?

Any other suggestions to try would be apreciated.
From what I have seen so far, most of these features are very good.

Have tried running as Administrator on both computers as well.
No luck.
