Using Ssh - D-Link NetDefend DFL-CP310 Cli Reference Manual

Using SSH

NetDefend users can control the firewall via the command line, using the SSH
(Secure Shell) management protocol.
By default, SSH access is allowed only from the internal networks. You can allow
SSH access via the Internet, by configuring remote SSH access.
Note: The NetDefend firewall supports SSHv2 clients only. The SSHv1 protocol
contains security vulnerabilities and is not supported.
To enable SSH access from the Internet
1. Log on to the NetDefend Portal.
For instructions, refer to the User Guide.
2. Click Setup in the main menu, and click the Management tab.
The Management page appears.
3. Specify from where SSH access should be granted.
See Access Options on page 12 for information.
Warning: If remote SSH is enabled, your NetDefend firewall settings can be changed
remotely, so it is especially important to make sure all NetDefend firewall users'
passwords are difficult to guess.
If you selected IP Address Range, additional fields appear.
4. If you selected IP Address Range, enter the desired IP address range in the fields
provided.
5. Click Apply.
You can now control the NetDefend firewall using an SSHv2 client.
