I am setting up a firewall with natd on my FreeBSD system, and for some reason
it does not seem to be translating the local LAN addresses in outbound
packets.

FreeBSD router w/ two NIC cards:
Internet card xl0 - 216.30.xx
Local network vx0 - 192.168.0.x

natd is running on xl0

I can generally access the outside world OK from the LAN, but certain services
(DNS and PCanywhere requests, among others) receive packets back addressed to
the LAN.  These hit one of the first rules on the firewall, deny any destined
for 192.168 networks.  

I have tried running natd with the -n flag and the -a [ip address] flag but
still get packets back on the external iface addressed to the 192.168
addresses. 

Anyone run into this before?
