Ahh but I already tried physdev - and it throws warnings that it will
not work on forward or post routing paths when it's not on a bridge

But I was specifying the rule with "-o br0" which is a bridge so the
physdev rule should have been sane?

Even though it threw this warning it did add into iptables but still
didn't work for me.

I might revisit it and see if I can figure out what was wrong.

The iptables physdev match will probably save your day.
