How to use Winsock control in a Broad band router

Hi,

I have used the winsock control before, but only on Dialup connections where the network IP address of both the server and the client (my PC) was known.

But now I have a broadband router that connects to the internet, my PC is connecetd through a LAN, the IP address is obtained dynamically.

I would like to know how I can make applications that communicate with each other on the internet using the Winsock on such networks ???

Your help will be much appreciated..........

thanks

You have to port forward!!!

If is port 80 ur usein the 80 -> 80

as the person trying to access ur IP on port 80 ..

will use 80 an be forwarded to 80 .. I know a bit complicated ..

Any ways a google search .. on it will help .. more

Try http://portforward.com/

Basically you go into the router and tell it which port number to forward to which computer for incoming connections. (Outgoing connections - those you initiate - don't need to be forwarded. Only those requests initiated by another computer - and one outside your router - need to be forwarded.) Then you use the winsock control the same way as before, using your external IP address (connect to http://www.whatsmyip.org/ to find it) from the other computer. (From your computer your IP address is always 127.0.0.1, or you can run ipconfig from a cmd window to see your actual internal IP.)
