Access Control List (ACL)
The modem can be configured with Access Control List to prevent un-authorized incoming IP traffic.
Please refer to the "Getting Started with ACL" application notes for further details.
Note
ACL cannot only be configured and managed via AT commands.

Password protection
This feature allows administrators to restrict unauthorized users from configuring the modem by requiring a password
whenever the modem's configuration ports are accessed.
To enable password protection:
1)
Navigate to CONF (Modem Configuration) > Password and check the "Enable" box.
2)
Select the interfaces to prompt for a password on. The WAN interface (remote connections) is the most
commonly password-protected interface, however some users may wish to password-protect both the WAN &
LAN interfaces. Note that the modem cannot prevent configuration changes made from its serial port.
3)
Finally, set the modem password. The password must be a case-sensitive string that is 6-30 characters long.
