Hi, I have need for a transparent filtering bridge. I have been using OPNsense for this earlier following this tutorial:
https://docs.opnsense.org/manual/how-tos/transparent_bridge.html
It seems to be pretty old - and it even says it "setting should apply up to at least 17.1.6.".
I have followed the tutorial with OPNsense 22.1.2_2 but it seems like some Chrome/Edge traffic gets through due to the rule "Allow everything out of the firewall".
I wonder if anyone has a newer/updated tutorial to share or why this one isn't getting any attention, the functionality is really awesome 8)
