I am attempting to setup port-forwarding on my Asus router so that I can, among other things, SSH to one device connected to LAN from the Internet.

Since my Internet provider doesn't provide me with a static IP, I setup DDNS with no-ip.com - I configured the provided hostname in my router's DDNS settings with the username and password. When I look at the no-ip.com dashboard, I can see that the target is correctly showing up as my router's public IP (in the form 100.100.xxx.xx, which matches the IP I see in the router config page).

In the router's port-forwarding config, I set it to listen to both UDP and TCP on port 500, forwarding the connection to the IP of the local device I want to SSH to on port 22. I setup a SSH server on the target device (listening on port 22), and added an exception for port 22 in the device firewall.

Now, when I try to SHH to the device (using the command ssh usernameplaceholder@noiphostname@ddns[email protected].net -p 500), if I'm trying it from another device connected to the same LAN, the connection succeeds. However, if I enable the VPN service I use on that device, or try to execute the command from a device connected to a completely different network, the connection times out. Likewise, if I try to run the command Test-NetConnection noiphostname.ddns.net from PowerShell on a Windows device, the ping fails/succeeds in the same fashion as the SSH connections.

Anyone that could help me troubleshoot what's going on?
