How can i port forward?

Question

Ok i have a Arris TM205 and i cant figure out how to forward the port,and i cant find out what my port is.lol im not sure if im wording this right but that is also because i hate networking and i kno very little about it.Ive tryed IPconfig/all and that wont work.any ideas?

Answer 1

Forwarding a Single Port

Put a checkmark in the Enable Virtual Server checkbox. Enter the ip address to forward these ports to into the Private IP box. If you are forwarding ports so you can run a program on your computer, you should enter your computer's ip address into that box. Enter the port to forward into the Private Port and the Public Port boxes. Use the Type drop down box to select the protocol type of the ports you are forwarding. Enter the name of the program into the Comment box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded would be a good idea. When you are finished, click the Add button.

Most people will never need to use this, but I'm going to explain why they have Private Port and Public Port here. The Private Port and Public Port entries are actually rather useful. They are there so you can direct traffic at two computers on your network. Let's say that you have two computers running Ftp servers on your network. Let's call these computers computer one(192.168.2.10) and computer two(192.168.2.11). Let's also say both these ftp servers are running on port 21. Okay we setup your router to forward port 21 to computer one(192.168.2.10:21). So every external ip address request from ftp goes two computer one. How do we get to the second computer? Well the Private Port and Public Port entries allow us to specify another outside port to connect to our internal port 21. Lets make the additional port, port 30. We would now setup a rule in the router with the Public Port set to 30 and the Private port set to 21. The ip address in that rule would be 192.168.2.11. So when you wanted to ftp to computer two you would specify port 30 in your ftp client. The router would see these requests coming in on port 30 and forward them to (192.168.2.11:21). This would allow you to ftp to both computers.

Answer 2

Isn't the TM 205 a MODEM?  If so you don't port forward all ports are forwarded!  You just need to open ports in your firewall on your computer.  I haven't seen any Arris routers, not to say they don't make one but I haven't seen any.

Here is a great site on portforwarding - http://portforward.com

You can learn alot there. BUT in your case I suspect all you need to do is set your computers firewall to allow the ports you need (or to allow the program access).
