Hi
Think their might be a problem with this patch.
Potientially a packet could traverse the pre, forward and the post
routing, at which point it can be SNAT'ed or MASQ'ed and then re
injected into route_me_harder. This potiential could allow packets to
be rerouted based on the new src/dst addresses differently to the intail
packet but this new packet doesn't traverse any of the chains with the
new information.
