2018年9月16日 · You cannot change the port number for the Windows built-in VPN. The most you can do is use port-forwarding on the router. I believe that this is possible if you use OpenVPN instead of using Windows for both server and client.

Here are the ports and protocols: Protocol: UDP, port 500 (for IKE, to manage encryption keys) Protocol: UDP, port 4500 (for IPSEC NAT-Traversal mode) Protocol: ESP, value 50 (for IPSEC) Protocol: AH, value 51 (for IPSEC) Also, Port 1701 is used by the L2TP Server, but connections should not be allowed inbound to it from outside. There is a special firewall rule to allow only …

From what I have found, it seems that port 1723 is the main port to forward, but I also see numerous references to others ports. The server that is hosting the VPN is a Windows 2008 Server.

I need to check that an OpenVPN (UDP) server is up and accessible on a given host:port.

I searched and I am told that "port 1723" or 'GRE protocol port 47" being blocked can cause this issue as well. How can I check them and, in case they are blocked, unblock them?

2021年6月24日 · Using applications like qbittorrent and airdcpp to share files. They all need some ports to be forwarded in order to be "connectable". In the home connection I would go into the router se...

You can change SSTP port after VPN server stopped. I tested. Also, windows client needs special treatment: 1. add hosts rule pointing to localhost by remote server name 2. add port redirection to vpn server use netsh interface portproxy add
