Ok, I used the arrangement of page 17, set the sclientinfo ip to my wan (the one that ipchicken gives me right?) but now, I cant acces the server, my friends neither, if I change all the ips to the server's local IP. I can acces the server (cause I'm im the same router as the server), but my friends cant!
any suggest now? should I use No-Ip? cause my internet connection is: Router -> Hub -> W-Router -> Server and My computer
