Chapter 26 Remote Management 461
After the identification is verified and data encryption activated, a secure tunnel is
established between the client and the server. The client then sends its authentication
information (user name and password) to the server to log in to the server.
26.7 SSH Implementation on the ZyWALL
Your ZyWALL supports SSH version 1.5 using RSA authentication and three encryption
methods (DES, 3DES and Blowfish). The SSH server is implemented on the ZyWALL for
remote SMT management and file transfer on port 22. Only one SSH connection is allowed at
a time.
26.7.1 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.
26.8 Configuring SSH
Click ADVANCED > REMOTE MGMT > SSH to change your ZyWALL’s Secure Shell
settings.
Note: It is recommended that you disable Telnet and FTP when you configure SSH
for secure connections.
