Hi Jamie,

You don't use rules to do that - just edit /etc/rc.conf to launch natd with
the additional flags

-redirect_address -redirect_address

Subject: NatD question

I have an odd(?) NatD setup I am tryin to implement but haven't been able
get it working or find adequate resources to help me figure it out.

I have a cable modem, and with it I am assigned 4 IPs. Now, as they
are not IPs I can subnet, and because I want some basic firewall functions
(Blocking NetBios, for instance.), I want to connect the cable modem
to my FreeBSD server, then connect a second NIC to a hub on which rests
2 other machines.

This part i have wokring ok. What I want, though, is for those two machines
to be accessible from the outside world as public IPs through transparent
translation on the FreeBSD box.

So what I have is:

  The Internet
| Cable Modem |
                                      | |
                                      | |
                                      | |
                                      |               |
                                      | |
                 /-------------------------| Hub |
                 |                         \-----/
          /--------------\                    |
          | |                    |
          \--------------/                    |
                                       | |

Where do I begin in writing the NatD rules that will allow packets destined
for hit, and for machines on the internet to see as when sending packets back?
