port forwarding + Masq. (localnet to localnet).

Post by cmo » Mon, 27 Mar 2000 04:00:00

I got a few questions.

Is there a way to get ipchains masq. to kick in before
ipmasqadm portfw  ??

What is the difference between ipmasqadm portfw and
ipmasqadm fwd ?
I know the second you need to mark the packets as

disadvantages between them ?

Thanks for any help.
