DDNS with No-IP does not work

Question

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.

Please guide?

Solution

The reason you're seeing failed pings is that DD-WRT blocks anonymous ping requests by default (any competent router should do this as well). It helps to prevent people from "seeing" you on the internet, therefore improving your security a little bit.

You'll likely need to open and forward ports, depending on what you're planning on doing.

You can't ping because you only forwarded 80 and 22. The ping stops at the router, as it should.

Any way to unblock it?

@Ali Sure, but I'd highly go against this. It's in the Security page. Untick Block Anonymous WAN Requests (ping).
