you can't really "open a port" like magic. the way a port opens (or the most common way) is by running a daemon (a program, such as your router program, or ftp, or ssh, etc), and it binds itself to a specified port. i hope that makes more sense. if you want to change what port it is on, you should look in the configuration file for your program, *or* you could try using a port-forwarding technique i guess ;o) actually, yeah- it looks like portfw is what you want.. i think you might be able to start at http://www.fandelem.com/nhf-5.html#portfw but you might want to do some more research also.. i'm in class at school right now so these are just my thoughts after a first thought ;o)
