I'm connected through a linux box running smoothwall, I've just set up port forwarding to allow TCP and UDP ports through so I can use a primary connection. It seems to be working fine I can DL but I can't UL (nobody can get any files from me).

When someone tries to get a file from me I get a "waiting for incoming connection" message, nothing happens and eventually the connection times out.

Does anyone have any suggestions as I don't want to be a leach......
