I want to access my home machine from internet. Since I don't have a static IP I am trying to use DDNS. For that, I've registered a free domain(alihammad.ddns.net) with Noip.com, it binds my external IP (101.50.xx.x) with the domain name. I've also configured my router DDNS settings
Router: TP-Link TL-WR740N Routeer Firmware: DD-WRT v24-sp2 (11/21/10) std
I am also forwarding two ports, 80 for web and 22 for ssh.
Now if I ping my domain (alihammad.ddns.net) from LAN, it works. But, if I ping the same domain from another network, it doesn't work.
