According to Mel Seder:
Id like to use the following services and forward the applicable ports. I used to know the password to my router softwear at 192.168.0.1 but I don't anymore. I thought I did but it doesn't look I do.
You may have to do a reset on the router box, then, to restore factory defaults, which means you'd have to reconfigure all the settings you had changed previously.
Part of my problem is that bittorrent seems to be running along fine and then all of sudden the speed starts dropiing toward zero and eventually stops working (even a Control-C) doesn't exit the app. However if I remove and restore power to my router the download seems to magically start working again. So I figured I'd see if there was newer router firmware and specifically open up Bittorrent ports at the same time.
Would you please let me know the ports for the following and any other items you think might me useful?
FTP SSH
You'd only need to configure these if you want to allow FTP and SSH connections _in_ to a system behind the router. SSH is easy: it's tcp port 22.
FTP uses tcp port 21 for the control connection, and port 20 for the data connections, assuming you're using active-mode FTP. Since many FTP clients now use passive-mode FTP by default (to make it easier to work when going _out_ through a NAT-based router), you might have to enable an additional range of ports to allow for passive connections. Depending on which FTP server you set up, there may be a way to limit it to a particular range of ports for passive connections, which should (of course) match the settings on the router.
Bittorrent
According to the URL I provided earlier...
http://torrent.dulug.duke.edu/
"Open up ports 6881-6999/tcp so other clients can contact you for bits"
I would assume this is the only port range you need to open up on the router to fix the bittorrent problem.
If you know of a well done sight that lists other common ports would you please send me the URL.
Well, I usually consult /etc/services first, but not all of the ports you might want to know about will be listed, and those that are there may not be very well understood, since there's no description or reference info.
Here are URL's to some sites I've come across, which may be of use...

No single list I've found is exhaustive, but by looking at a few, you're likely to find a decent description of whatever port numbers you're looking for.
