Hello
Forwarding ports on a wireless network is slightly more complicated then opening ports normally, but not too hard.
You should forward the ports in your wireless router, not the modem.
What you need to keep in mind is that you need to get your computers internal IP and make sure you forward them to that internal IP and correct port.
Its really easy to follow Portforward.com's guide for opening ports if your router is in their list.
http://portforward.com/english/routers/ ... rindex.htmChoose your router, then choose your program (utorrent) remember to skip the add for the automatic portforwarder they display sometimes and go to next page.
If you cant get it to work get back to me and I will help you step by step.
