uTorrent won't download on a second PC getting internet from first PC

[utilae]

Hi, I have two computers. 1st computer has Windows XP Pro and an internal adsl modem (not a router). 2nd computer has windows XP Pro, gets its internet access through internet sharing (1st computer is like a server). Both use windows firewall. Both uTorrent clients are v1.7.5.

I have always used uTorrent on the 1st computer, and I have never needed to do port forwarding on it cause of the internal modem. When I try downloading through uTorrent on the second computer it doesn't download. The Speed Guide setup screen says that a port is not forwarded.

I am not going to have both uTorrent clients going at the same time, but I will optionally choose one or the other whenever I want.

Any idea how to get this working?

Thanks
