Overview

This article covers how to enable a LAN bridge in pfSense®. LAN bridge act as a switch using the optional ports on the Vault. While not optimal compared to using a separate physical switch, it works if needed.

Note: If the port being used for the web interface is added to the bridge, then physical access to the unit will be necessary.

How to Create a LAN Bridge in pfSense®

In this example we will be assigning the LAN interface to a bridge utilizing the Vaults additional ports, OPT1 and OPT2. The idea of this example can be used across all the Vault models with small variation.

  • Access the webGUI. The default IP address: 192.168.1.1, username: admin, password: pfsense
  • Verify the Vaults optional interfaces(OPT1, OPT2, etc) are assigned with default settings.
  • To assign simply click Add next to the port you wish to assign. Click Save.
