Unable to open any incoming ports by configuring a virtual server. PC behind router is Win10-64 v2004. Have contacted the ISP and they claim to only block incoming port 25 - and all others are open. Internet browsing works without issues. There is an SSH server on a PC (192.168.1.100) attached (wired) to the router. The SSH server is configured to use port 222 - incoming and outgoing. The outgoing SSH client functions normally and I can access remote machines via the internet connection. Configuring a virtual server for 192.168.1.100 with both incoming and outgoing ports set to 222 does not result in an open incoming port being visible. Using https://canyouseeme.org/ to check open ports. Setting 192.168.1.100 as a DMZ and rebooting the router does not open any ports - including 222. When pinged from a remote machine, the WAN IP address times out. Dynamic DNS (on the PC with the server) updates properly but the WAN:222 is not visible from the internet. However - enabling 'Remote Management' in router administration opens Port 443 and that port is visible using a port check tool. Disabling closes that port and it is then no longer visible. Help configuring the router would be appreciated.
Check that your public IP address is what you're using to access your SSH server from outside your network: https://www.whatismyip.com
Ping <yourname.dyndns> domain and compare the IP address responding, with the previous result - they should be the same.
Configuration on your router:
Finally try to access your SSH server from your internal network to be sure it's working on TCP port 222.
@Ivaylo Thanks for the response Ivaylo. Yes - I am connecting to the proper IP address. That is why the 443 port is visible when Remote Management is enabled. The IP shown by whatismyip.com matches what the router says it is. However, https://www.yougetsignal.com/tools/open-ports/ shows that 222 is closed at that same IP.
The only thing I find odd as when using https://www.yougetsignal.com/tools/open-ports/ - if click 'Check' again (quickly) while the first check is running - it shows the port is open. That might indicate that the ISP has some layer of 'security' that masks the real IP of my SSH server. That behavior can be duplicated.
Virtual server is set up as shown in your post - only the protocol is set to All.The SSH server is accessible locally and can be configured. The client for that server is able to access other (remote) computers via port 222 from the same box as has the SSH server installed.
Try to move the external port higher - for example TCP port 60222 and see if that helps:
Then try the external access on TCP port 60222.
Any intermediate device between your ISP and your router ? Are you using it as 4G+ or regular router ?
