3.3.6 Listener Ports
The SoftEther VPN Server enables multiple TCP/IP ports to be set on standby and VPN client computers can then establish a VPN connection and VPN session with those ports via an Internet or other IP network. That is why it is essential for the VPN Server Administrator to register the listener ports in advance.
Initially, the three TCP/IP port numbers 443, 992 and 5555 are allocated to the VPN Server as listener ports. While as many listener ports as system resources allow can be added, typically one or two ports are sufficient.
We recommend using TCP/IP port 5555 to connect to the VPN Server where no hindrances exist, and port no. 443 where there is a firewall or proxy server which only allows web or other partial protocol to pass. Port no. 443 is a port for https protocol, so performing SSL transmission on this port usually enables passage even on networks with stringent security settings. Meanwhile, 992 is a port number for the TELNET over SSL (Telnets) protocol, which is practically unused today, and can pass through most firewalls (although it often fails to pass through proxy servers). It is also possible to register several listener ports and then disable some of them (suspend status).
To add, delete, enable or disable listener ports, click on [Create], [Delete], [Start] or [stop] at [Management of Listeners] in the VPN Server Manage. In the vpncmd utility, the same tasks can be carried out using the [ListenerCreate], [ListenerDelete], [ListenerList], [ListenerEnable] or [ListenerDisable] commands.
When launching the VPN Server, all registered listener ports which are not disabled are opened and put on standby. In addition, registering new listener ports also sees those ports automatically put on standby. If a port cannot be put on standby, an [Error] message will be displayed until the other process exclusively using that port is terminated or until the port is released, and the VPN Server automatically secures the port once either of these happens.
Mình đã tìm hiểu và không biết làm để chỉnh được Listner port hết
Bạn nào sửa được thì hướng dẫn giúp mình với. hay có thể share cho mình cái "VPN connection setting" để mình import được không ??
thanks
