I think the way to go is to have a ip rule option in which the admin can
add routes which get consulted only by the icmp source address
determination logic. I can assume that some other installations use
other interface number logic or multiple public addresses. This kind of
lookup seems to allow all possible lookup scenarios.
Thoughts?
