recent match and DNAT.

recent match and DNAT.

[Wakko Warner]

Is it possible to use the recent match and dnat to dynamically forward
incoming packets destined for a specific port (ident in this case) to the
machine that initiated the connection?  Or is anything like this possible at
all?

There may very well be a way to do it, but if there is, I can't 
seem to find it, and I know of at least one other person who's 
messed with it.  Best I can tell, midentd on the gateway is going 
to be your best option.
You might find this useful as well - I wrote it up quite some 
time ago, but coupled with midentd, I think you'll have a 
workable solution.

I was looking for a pure netfilter way of doing it.  But it's no big deal
really, I have ident forwarded to one machine which is most likely to be the
source of the outgoing packets anyway.
