Net Library Over The Internet

RywesTech

Hello everyone, I have made a messaging program that allows users on a LAN network to connect to a server, and talk by typing messages. I would like to expand this to where my friends (at there house) could connect to my server (at my house) and be able to chat. I have already forwarded my ports from my router, but cannot get the client program to connect to the server over the WAN IP of my house. I believe that I just need the client program to know to search outside of the LAN network for the server. Does anyone know how to do this?

Thanks, RywesTech.

FYI, I have also searched the forums and google for an awnser, but have found nothing.

• Clients connect to the WAN IP, which reaches the server's router.
• Then the router forwards the connection for the server's internal LAN IP.
• Most common strategy used is set ports to specified LAN IPs.
• Another 1 is activate DMZ for 1 chosen LAN IP.
• There's also UPnP dynamic port opening.

Thank you GoToLoop for replying so soon!

I have already opened the correct port for my server, my question is that the client program when I put the wan IP for the server in, it does not connect. How can I make it connect over WAN?

• AFAIK clients don't need anything but server's WAN IP or corresponding URL.
• Perhaps your server is using a port which isn't 80?
• In that case, clients also need to specify the port as well.

Yes, all of my port number are correct — the port forwarded one, the server one, the client one

Now I am on my laptop, witch I only have one port forwarded, and it works!!!

Looks like you can maybe only have one port fowled per computer?.?.?..?...

Inside a LAN, each device has its own IP. Therefore port forwarding works w/ 1 device at a time. :-B
Of course we can assign as many ports to 1 single IP! :-c
