I've got NAT, now how do I get it to work?
Brent P. Newhall
the life of me get NAT working for my home LAN. I'm hoping some of you
would be willing to give me some hints. :-)
I have three computers on the LAN; two BeOS machines (192.168.0.1 and
192.168.0.5), and one Windows 98 machine (192.168.0.2). I'll be using
192.168.0.5 as my main system from now on, so I wanted to use that as a
NAT gateway. I can ping, telnet, and FTP between all of these machines
with no problem.
I downloaded NAT and unzipped it on 192.168.0.5. The instructions on this
official page:
http://www.rickb.com/ricksoft/nat.html
say (among other things) to copy the executable "nat" to
/boot/beos/system/add-ons/net_server, which I did. I left the rest of the
unzipped files where I'd unzipped them. I then went into Be ->
Preferences -> Network, click on the Services tab, clicked "IP Forward" to
make it checked, and restarted networking. So far, so good.
I then went into both of the other computers, and set up the preferences
in both of them to use 192.168.0.5 as their gateway. Windows required a
complete system reboot, of course, while BeOS only needed to restart
networking. OK.
I then went into the .5 computer and (after setting it up to see itself as
the gateway), fired up dial-up networking and connected to the internet.
No dice. Neither of the other computers can so much as ping the outside
world.
What might I be doing wrong? Any help, suggestions, or requests for
further information would be greatly appreciated.
Thanks in advance.

Did that before; sorry, I should have mentioned it. I kept the defaults
and turned NAT on, then restarted networking. Sadly, there's no
discernable effect that I can see. :-/

You have to configure NAT using the NATConfig utility (it's in the NAT
archive).

Ah, ok.
Then I try describing my (working) setup:
I have a linux box (192.168.0.1) and my BeOS box (192.168.0.2) connected
together using a 100MBit LAN. The linux box uses the BeOS box as default
gateway. On the BeOS box I configured only the hostname, the IP address
and the subnet mask in the network prefs. All other fields are left blank.
In NATConfig I have the BeOS network address (192.168.0.2) in the LAN
field and PPP in the Internet field. Then I checked 'NAT On' and restarted
networking -> worked flawlessly ever since.
