Where the packet gets delivered is decided by the routing - and the very
first table traversed is local - which is auto filled by the kernel. But
that routing rule still can be forcibly removed, after which the next
matching one is the one added manually - after which the packet will end
in FORWARD, instead of INPUT.
(and keep in mind earlier David's warning about confusing
programs/services - it's still doable, but requires more manual labor -
proxy is certianly cleaner and just works)
