Have 2 Win/XP PC's and 1 Win/98SE

1. When I connect the two Win/XP PC"S using crossover cable, I can config
Win/XP to share dialup inernet - works great

2. to share resources and have common backup I have setup the 3 PC's on a
router - for sharing and backup works great.

3. but I cannot get dialup internet to share over the router, i.e. have one
Win/XP dial the internet, and the 2nd Win/XP PC get to the internet thru
that path.

Anyone have any ideas????

Thanks -
