LAN Bridge not responding to DHCP and not passing traffic



  • I'm attempting to follow https://www.netgate.com/docs/pfsense/book/bridging/bridging-and-interfaces.html#quick-but-tricky-reassign-the-bridge-as-lan to create a LAN Bridge. This results in any hosts connected to the member interfaces not being able to get a DHCP address or if a static address was configured, they are unable to ping the LAN IP. I've clicked all of the Apply Settings buttons and rebooted for good measure.

    Here is the config diff from a clean install, it includes a rule for allowing access to the web UI from the WAN interface.

    Any suggestions? I'm clearly missing something. 😞
