System Hardening

After confirming that all gateways and wireless drivers are working, you can secure or remove any unsecured IPv4 ports from each device.

This procedure is optional but highly recommended to maintain network security.

PDZG-E

Secure PDZG-E Routing:

  1. In System view, select the PDZG-E and open the Routing editor.

  2. Check the From and To fields for each entry, and replace the unsecured sb icon port ipv4 IPv4 Trunk port (50000) to the secured sb icon port ipv4 IPv4 Spur port (50443).

  2. Select the sb icon port ipv4 IPv4 Trunk port and modify the following properties:

    • Port Number: from 50000 to 51443 (This is the default port for secure trunk connections).

    • Secure port: from False to True.

If there are any other unsecured sb icon port ipv4 IPv4 ports, select each one and click sb icon delete Delete.
Save changes to the PDZG-E:

  1. sb icon save to device Save modified device data (Shift+F12) to the PDZG-E.

  2. Wait for the device to update and reset, and then click sb icon send device sign on Send Device Sign-On (F6) to confirm that it is connected and operational.

PDDEG-S

Remove unsecured PDDEG-S ports:

  1. In System view, select the PDDEG-S and open the Ports editor.

  2. Select each unsecured port (including the UDP Client and any Port 5000x entries) and click sb icon delete Delete to remove.

  3. sb icon save to device Save modified device data (Shift+F12) to the PDDEG-S.

  4. Wait for the device to update and reset, and then click sb icon send device sign on Send Device Sign-On (F6) to confirm that it is connected and operational.

  5. Select the PDZG-E and click sb icon send device sign on Send Device Sign-On (F6) again to confirm the PDDEG-S is still routing its messages correctly.
