Hi. I have a bridged topology and want to match bridge interface on mangle/POSTROUTING chain. I can add a rule like this. iptables -A POSTROUTING -t mangle -m physdev --physdev-in enp0s3 Then I figured out packets aren't matching and I saw this warning on dmesg. xt_physdev: using --physdev-out in the OUTPUT, FORWARD and POSTROUTING chains for non-bridged traffic is not supported anymore Then I just tried "-o enp0s3" and that didnt work either. I wonder why this feature isnt suported anymore? And Is there a way that I can match by interface on POSTROUTING if I have a bridged topology?
