I'm really familiar with the socket function ! :). This won't work if the client connection come from the internet over a Router you'll obtain the ROUTER IP !

I have used sockets over routers before, and have never had an issue with only getting the router ip....

Alex,

The problem wasn't getting my OWN IP, the problem is getting the IP from a client connected to a TCP/IP server that I wrote when the server is behind a ROUTER !

So you want to get the IP Address from Client A, connected to server B, while you are at client C, connecting to B?

Can't server B keep a record of who's connected?

simpler than that, I just want the IP adress of the client that his connected to the current socket descriptor of my TCP/IP server when behind a ROUTER.

Well, isn't that what oSocket:clientip() gives on the server? It does for me...

Alex,

It won't if your server is behind the ROUTER and the client connect to your server from the WAN you'll receive the ROUTER IP not the client IP
