Define Web, REST, Telnet, and SSH Authorized Management Access List

Allow only specific management clients (IP addresses) to access the Web, REST, Telnet, and/or SSH management interface types. The device denies access from undefined IP addresses.

The first authorized IP address in the list must be your computer's (terminal) IP address; otherwise, access from your computer will be denied.
The management access list relates to OSI Layer 5 (Session). However, you can also add firewall rules for Layer 3 (Network) and Layer 4 (Transport) with bandwidth limitation to limit access to management interfaces (see Block Unused Network Ports ).
To configure management access list:
1. Open the Management Access List table (Setup menu > Administration tab > WEB & CLI folder > Management Access List).
2. Click New and configure a management access list rule:

access

3. Click Apply.
