Winsock over the internet

Can anyone help me with this question:
can a winsock client application connects to its server which is not within the same local network?

Yes, Winsock works over WAN(the Internets).

So it means i can send you a copy of my client application and you can connect from there. i did tried this yesterday with a friend who's about 300km away from me and it never work out.

Firewalls, NATs, etc....

You have to ensure ports are being forwarded from the external gateway(typically a router/modem) in order to receive incoming connections. One easy way is to set your local IP to the DMZ, and this will forward all traffic to your local IP.

A local IP is just that(like 192.168.0.*, or 10.0.0.*...), then a router or NAT is responsible for routing traffic from your WAN IP to your local adapters.

if you have any client application setup kindly send it to me so i can try to connect from here

Here's a small program I wrote which allows you and a friend to establish a little shared virtual white board, where you can both draw whatever you like.

Sure, I'll PM you my IP, if you like, just drop me a message when you're ready.

I release it to the public domain, without license. Enjoy.
