can you specify incoming *AND* outgoing NIC on a FORWARD rule?

can you specify incoming *AND* outgoing NIC on a FORWARD rule?

[Christian Seberino]

FORWARD only table where rules can have -i *and* -o ??

It seems to make sense that you could specify 2 NICs
with FORWARD but not with INPUT or OUTPUT.

Is that right?

You beat me to the punch.  That is exactly what FORWARD does in allowing you to specify an inbound (-i) and outbound (-o) interface.

Forwarding is about passing packets from one nic to other.
INPUT and OUTPUT are between a nic and the host itself.
The packets not destined to or coming from your machine do not pass
through INPUT and OUTPUT chains.
