I have been trying to setup SoftEther for a while now but when I try to connect using TCP connection it is failing. So I tried to run a external scan to determine which ports are open and it seems all the ports which I have opened on my router for port forwarding is shown as closed. I was wondering could the ISP somehow disable port forwarding? If this is the case how can I verify it?
This is done on the laptop running the VPN server. As you can see in the bottom port 5555 is open.
The image below is on the router which connects to the ISP. As you can see port 5555 is not showing
The screenshot below is for the port forwarding page in the router as you can see port 5555 is being forwarded. But I am not able to use any of the other ports which are forwarded as well. Also with turning off the firewall
However for example if I try to log on using a local IP I am able to log in but cannot log in when I try to log in from outside the network. My ISP says they are not blocking any ports.
