I am attempting to establish a connection between two computers using MSDN codes:
Client code: http://msdn.microsoft.com/en-us/library/windows/desktop/ms737591(v=vs.85).aspx
Server code: http://msdn.microsoft.com/en-us/library/windows/desktop/ms737593(v=vs.85).aspx
These codes run perfectly on a local network, but my intention is to establish a connection over the internet, where both computers are behind routers. I know port-forwarding is a viable solution. But I just don't know how.
I am unable to properly configure my router to port-forward. Its model is Level One WBR-3407a. I tried this guide: http://portforward.com/english/routers/port_forwarding/LevelOne/WBR-3407a/defaultguide.htm But it didn't work. As you may note, this guide doesn't anywhere in it specify what port to use? is it possible to port-forward without specifying which port to forward?!

Predefined by the manufacturer? So there are ones that I can already use? – kalkanistovinko – 2014-08-27T22:10:56.933
1Yes. That's what your guide says. Classics like 80 (aka "Web"), for example. – Daniel B – 2014-08-27T22:12:48.423
The guide doesn't mention any. How to know them? – kalkanistovinko – 2014-08-27T22:15:07.273
2They're in the last screenshot. But seriously, get a new router. They're cheap and way more powerful these days. – Daniel B – 2014-08-27T22:18:36.820
1@kalkanistovinko WEB,POP3,SMTP are TCP- 80,110,25. FTP is 21 but possibly not just 21 maybe 22 too. DNS is UDP 53 (maybe can be TCP 53 not sure). So in short, it looks like you def have ports TCP 80,110,25,21 available to you to choose to do port forwarding on. It should work whatever is running on those ports. so you could run a whatever server on port 80 doesn't have to be a web server. – barlop – 2014-08-27T23:09:26.590
