Overview

Where there is a need to upload MAC addresses in bulk, it can be done manually by modifying the Kerio Control configuration file. The standard procedure involves adding MAC Addresses through Administration interface -> Configuration -> Security Settings, which might be not efficient for adding multiple addresses.

Solution

1. Login to Kerio Control through SSH, local console, or serial console (for Hardware boxes).
2. Make the system read/writable by executing the command:
   mount -o rw,remount /
3. Open /opt/kerio/winroute/winroute.cfg and locate a list called MacAccessList.
4. Add the necessary list items in the following format:
   
   where Desc is Description field and Value is the Mac Address itself in HEX notation, with no separators such as semicolons, hyphens, etc.
5. Save the changes and restart the main process:
   /etc/boxinit.d/60winroute restart

Testing

Login to Kerio Control Webadmin and verify the addresses were added successfully.
