Ok people, ive got a serious problem here.

I have a FreeBSD 3.2 box here setup as a gateway for a small LAN.

The internal network addresses are 10.0.0.x with a mask of 255.0.0.0

I have a external interface on this box as well with an outside address
of: x.x.x.x

I have a custom kernel compiled with the two required variables to run
natd.

I have a natd.startup script that runs on boot that enters all of the
required network configuration in and calls natd with the -f
/etc/natd.conf statement.  Within the natd.conf file are a the natd flags
I need for my network here, as well as some other commands.  

--natd.startup--

firewall_type="open"
firewall_enable="YES"

ifconfig tx0 x.x.x.x netmask 255.255.255.0

route add default x.x.x.x

if config de0 10.0.0.5 netmask 255.255.255.0

sysctl -w net.inet.ip.forwarding=1

natd -f /etc/natd.conf &

/sbin/ipfw -f flush
/sbin/ipfw add 100 divert natd all from any to any via tx0
/sbin/ipfw add 64999 pass all from any to any via lo0
/sbin/ipfw add 65000 pass all from any to any

--end natd.startup--

--natd.conf--

interface tx0
same ports yes
redirect_port tcp 10.0.0.6:8383 8383
redirect_port upd 10.0.0.6:8383 8383
redirect_port tcp 10.0.0.6:80 80
redirect_port udp 10.0.0.6:80 80
redirect_port tcp 10.0.0.6:110 110
redirect_port udp 10.0.0.6:110 110
redirect_port tcp 10.0.0.6:143 143
redirect_port udp 10.0.0.6:143 143
redirect_port tcp 10.0.0.6:25 25
redirect_port upd 10.0.0.6:25 25

--end natd.conf--


Please Help!  I've read the Complete FreeBSD on this, all man pages, and
scoured the newsgroups!  

TIA!

Christian
