hope this instruction can help, you should know which port you are going to open, or just enable DMZ instead.

I also need some help with server applications.

Torrent applications get automatically detected and added to virtual servers but there no incoming. I tried this with remote scanning but none of any manual set ports show open even in DMZ and static IP although it works fine with the older modem but there's more settings in this new one.

[UPDATE: Solved]

After a default reset and reinstall from the CD, all required server ports are open and working.

Im grateful for the forum topic.Really looking forward to read more. Fantastic. Parada
