Port 6112 (confused person with no technology knowledge)

[Freaky]

Ok, so I'm trying to play Warcraft 3: Reign of Chaos with my friend.
We're trying to do Arranged Team, but it says something about Port #6112 being closed, and that I need to open it. I have searched for a few hours on how to fix it. They always say things about make a port and TCP or something. I do exactly what it says, and my friend's computer is perfectly fine, they own a PC and are very technologically smart. Anyways, they also say to contact my ISP, but I am not good at talking to people about my computers. Please please help me. Also, if you can, I'd like if you explain it different ways..

I have an eMac, 10.3.9 if that helps at all.

We really want to play soon, so please answer

Are you using a router? If so, you need to change the settings. You need to make sure that port 6112 is available, and probably forward it to your IP.

I'm not sure what a router is.. sorry.
I have:

TCP (6112)
TCP out (6112)
TCP in (6112)
UDP (6112)

What do I do?

is your computer directly connected to a modem?

Yes, we do have a modem.

Yes, we do have a modem.

Is your computer directly connected to this modem? Or do you have a router which allows multiple computers to use your internet connection.

I asked my dad and he says no.
But when my brother and sister come home from college, they can connect their computers to the internet..

walk over to your modem, find the model number and name, etc..., and post it

There are several different numbers, so I'll try my best to do this right..
