Port Numbers for SSH and Telnet Connections in NSM Overview

 

You can configure the port numbers to use for SSH and Telnet connections:

  • The default port for SSH client connections is 22; to change this default, enter a port number between 1024 and 32,767.

  • The default port for Telnet client connections is 23; to change this default, enter a port number between 1024 and 32,767.

In a vsys system, the root and vsys share the same SSH port number. For example, if you change the SSH port from the default port 22, the port is also changed for all vsys.

Note
