Management port on transparent bridge

[mantissa]

This has been problematic for me. I have a transparent bridge running IP4 and IP6. The bridge is on OPT1 and WAN. The IP4 address space is on the OPT1 interface 192.168.1.0/24. Traffic passes fine between OPT1 and the WAN. I cannot get a connection outbound from the bridge0 device to the outside world. This means I cannot get updates or add packages. I have been managing the bridge via the LAN interface on 192.168.10.1/24. I suspect this .10 address space is the problem. I have tried a few things and ended up locking myself out a couple of times so I am kind of hesitant to play around with settings until I know what is going on. How can I configure the device to it can communicate out the WAN and get updates?

Have you done this : https://docs.opnsense.org/manual/how-tos/transparent_bridge.html#change-system-tuneables ??

And are you aware of the fact that the Management Interface is used for Internet Connectivity : https://docs.opnsense.org/manual/how-tos/transparent_bridge.html#connect-interfaces-to-existing-infrastructure !!

I cannot get a connection outbound from the bridge0 device to the outside world.

This requires, that the OPNsense has an IP the same subnet as the other devices, which are able to get out to WAN across the bridge and that the gateway is configured correctly.

The bridge tutorial linked above is more about transparent filtering bridges with vlans that should stay unnumbered. A normal LAN bridge should work as @viragomann mentions.

@Monviech for OPNsense to get out to the Internet in a transparent bridge setup it needs an IP address matching the other router and a properly configured default gateway.
