I have IPFW running as my firwall to the 'net with natd for the =
translation.

Problem is using natd with the divert socket to divert all traffic to =
natd,
you end up with a situation where you cannot use stateful rules (at =
least I
can't figure a way out) as an example:

Say an inside machine 192.168.1.10 connects to the outside world via =
IPFW,
with a public address of 196.6.128.200.  If I log the connection =
verbosely I
see the following:

Tcp outgoing from 196.6.128.200 - outside host:port for the outgoing =
packets
of the connection and
Tcp incoming from outside host:port to 192.168.1.10 (which is the inside
address)

Obviously the stateful rule misses the incoming packets with different
distination addresses, consequently the connection fails.

Any suggestions

Regards

Max
