37.8.2 SSH Implementation on the ZyWALL
Your ZyWALL supports SSH versions 1 and 2 using RSA authentication and four encryption methods
(AES, 3DES, Archfour, and Blowfish). The SSH server is implemented on the ZyWALL for
management using port 22 (by default).
37.8.3 Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating system)
that is used to connect to the ZyWALL over SSH.
37.8.4 Configuring SSH
Click Configuration > System > SSH to change your ZyWALL’s Secure Shell settings. Use this
screen to specify from which zones SSH can be used to manage the ZyWALL. You can also specify
from which IP addresses the access can come.
