The following works for me with fwtester:

# ./fwtester.pl -d test-basic1/tests vm2vm
IPT statistics: invocation = 3, checks = 33

When in add:

 -A FORWARD -j PVEFW-FORWARD
 -A  PVEFW-FORWARD -o vmbr+ -m physdev --physdev-is-bridged --physdev-out fwpr+ -j RETURN

# ./fwtester.pl -d test-basic1/tests vm2vm
IPT statistics: invocation = 3, checks = 30

So I guess we do not gain much here?

We just moved them the opposite direction?
