The NATd man page is pretty detailed, so is the handbook, but see below for some additional info.

Either you were successful or it failed. If is failed then you have to stop right there until you get a successful kernel build. >- I have add "natd 8668/divert #NAT Socket" to /etc/services >- I have added natd -interface rl0" in /usr/local/etc/rc.d/nat.sh You should not have had to edit the /etc/services file, it has had the natd entry in it since 3.x releases. >Question > >- What exactly do I do in "redirecting traffic" to natd to get the the >above FreeBSD 4.3 and Window 95 machines to work? Complete steps to set-up NATd on a 4.3 install: Make sure your FreeBSD box has TWO network cards in it. One should connect directly to your cable modem and the other to your internal hub. Make sure both interfaces work and that you can PING the FreeBSD box from your Win boxes and that your FreeBSD box can see the Internet via the cable modem. I assume below that you know how to use the "vi" editor. If not, use whatever you use for editing the files and disregard the "<esc>:wq<enter>" steps. As root: # cd /sys/i386/conf # cp GENERIC CUSTOM # vi CUSTOM make any changes you need to and add these lines: options IPFIREWALL options IPDIVERT <esc>:wq<enter> # /usr/sbin/config CUSTOM # cd ../../compile/CUSTOM # make depend # make # make install # cd /etc # vi rc.conf add these lines: defaultrouter="x.x.x.x" firewall_enable="YES" firewall_type="open" gateway_enable="YES" natd_enable="YES" natd_interface="rl0" <esc>:wq<enter> # rm /usr/local/etc/rc.d/nat.sh # reboot Make sure you use your EXTERNAL interface (the one connected to the cable modem) in the natd_interface= above. The defaultrouter should be whatever your ISP told you. Set the default gateway of your Win boxes to the INTERNAL interface of your FreeBSD box. Look into IPFW if you feel unsure about running an "open" firewall. Look into adding DHCP for an easier time with your Win boxes.
