Why ? What do you want to achieve exactly ?
> Can a rule work out the IP address of its host?
What address ? A node may have more than one single address, and usually
does : typically the loopback address range 127.0.0.0/8 and one or more
addresses assigned to each "real" interface. If a packets arrives in the
INPUT chain, it implies that its destination address is assigned to the
node. Otherwise the packet is discarded if the node is a simple host, or
sent in the FORWARD chain if the node is a router.
