A technical article about configuring your YahooBB modem for port forwarding. This blog is certainly not intended to be a technical blog and I am not the best qualified person to write such a thing. But I wish I had found this article before I set out to forward a port from my router to one of my PCs. So it might be useful to somebody else.
I wish I had recorded my entire experience of setting up an Internet connection. But that was in the days before I considered writing a blog. Here is a handy site about YahooBB and getting it set up.
This article is about how to forward a port on your YahooBB router. This article is also not about port forwarding. There are lots of resources and people who can advise on this subject much better than me. So the preliminary section should be regarded as a rough guide written by a novice.
Finally, please note, lots of modern applications don't require port forwarding. Network applications we use at home: Skype, Messenger and Guildwars don't require port forwarding.
Some network applications would like to contact an application on your PC directly <list>. When they send a message to your router it won't know which PC on the network to send that message to. This happens even if there is only one PC on the network. This is frequently a security benefit because it means your PC is not exposed to uninvited incoming communication. This can also be a problem if you want that inbound communication to arrive at your PC.
To allow this communication you can enable port forwarding on your router. Basically this tells the router "when you get an incoming communication on port xxx, forward it to this PC". Don't do this unless you have a good idea what you are doing. A router is an effective security measure and "putting holes in it" is creating security risks. Certainly don't open more ports than you need to and it might well pay to do a bit of a search to see if the application that will be listening on that port has any security issues that should be considered. Also don't forget the target PC should have a static IP address.
My 4-G BB Modem
Redirecting the Port:
So once you know the port you want to forward and the static (fixed) IP address of the computer you want to forward it to you are ready to get started.
My router is a BB Modem 4-G (I know this works for some other models too. Visit the configuration page of your router by opening your browser and going to 172.16.255.254. If that doesn't work then either you are not properly connected to the router or things have changed and your router configuration page is not at that address anymore.
You should be prompted for a username and password. On my router they are "user" and "user". If that doesn't work then things have changed and those are not the username and password anymore.

Click on this menu item:
Now enter the port range you want to forward. If you only want to enter one port then just enter to and from that port number. Then enter the port number you want to map those ports too (in most cases the same entry as the port range above). Then enter the IP address of the PC you want to forward those ports to. Once you are done go to the bottom of the page and click on "OK".
The procedure might be slightly different depending on the router that you have. But this works for me and has worked for others too.
I'll try to answer any technical questions that pop up here but you might also try the above link to get more minds working on any problems that you might have.
