Warcraft 3 can't transfer maps???

The subject just about says it all. We can can connect and play however if someone does not have the map it will not transfer just stays stuck on 0%. Any ideas. Anyone out there had a map transfer.
And on a seperate issue. The only way we've got git to work is that if all computers are 192.168.x.y where y is constant for all the pc's. Is there any special config for when the seperate lans have different y. cause we've tryed with the same settings that work for constant y and no go.
