[pve-devel] [PATCH 2/2] bridge rules : -j ACCEPT for physical interfaces

[Alexandre Derumier]

We need to accept traffic at the end of bridge rules for outgoing packets from tap->ethX,
as we don't do ACCEPT in tap-out rules.

IN=vmbr0 OUT=vmbr0 PHYSIN=tap110i0 PHYSOUT=eth0

-A PVEFW-FORWARD -o vmbr0 -m physdev --physdev-is-bridged -j vmbr0-FW
-A PVEFW-FORWARD -i vmbr0 -m physdev --physdev-is-bridged -j vmbr0-FW

	-A vmbr0-FW -m physdev --physdev-is-in --physdev-is-bridged -j vmbr0-OUT
	-A vmbr0-FW -m physdev --physdev-is-out --physdev-is-bridged -j vmbr0-IN
	-A vmbr0-FW -j ACCEPT

-A PVEFW-FORWARD -o vmbr0 -j DROP
-A PVEFW-FORWARD -i vmbr0 -j DROP
