Hi Joefuf.
Well my friend If you done all that & completed making a static IP.
then portforwad was done propley.
That leaves your connection setup CD OR your ISP filtering P2P
Filtering can be, say, 5 00pm to 11 00pm so if you tried your laptop at 4 00pm
It would work, then try your home comp at 5 30pm, Nothing!!
Ask your ISP if they say no, for that in writing.
Peace.
