Hello!

Does resurrection make a sense??
What are reasons to do this? iptables seem to do everything.

I made this trick in 2.2 because people (particuarly, me) wanted
masquerading to work and ipchains did not provide this facility
masquearading to a random address.

I am afraid it is not resurrection, but rather waking up a zombie.

It is intersting in any case. I even did not know that this is possible. :-)

No, I think. Actually, I planned to kill the match against everything
but priority. But the more I delayed this change, the more
it was cathastrophic. Well, look into ip-cref, it directly warns
about this change in future and prescribes to give an explicit priority.

But I will concentrate all the will and will do it in 2.5.
