Konnichiwa

Im Ishida Hiraga, and i have one problem with my ADSL Router.
I know that lot's of games explain detailed what ports the game uses in multiplayer games. This info usually are showed in the books or notepads of that games but i dont find them for Shogun Total War/Mongol Invasion.

If anyone knows what ports this game uses, please write them here and i can config my router to open that ports and finally i could host games.

Thanks for ur attention.
