Well, if you are planing to allow all three mchines to access the internett,
throgh the PPP account you must either get a full domain connection from your
ISP, or install a firewall on your linux system foling your ISP that there
is only one machine with the IP number. If you chose the first version you'll
probably have to change your local IP numbers.

In any case you have to configure your linux machine as a router. Which
meens that it needs two IP numbers, two networkaddresses, two
broadcastaddress, one for the eth0 interface and one for the ppp interface.
What values to use for the PPP interface should have been provided to you
by your ISP, and what to use for your eth0 interface is the same as for the
rest of the machines. I would guess something like:
eth0
IP=192.168.3.4
NETMASK=255.255.255.0
NETWORK=192.168.3.0
BROAKAST=192.168.3.255
PPP
IP=205.198.193.254
NETMASK=255.255.255.0
NETWORK=205.198.193.0
BROAKAST=205.198.193.255
The default gateway for your linux box should be the machine at the other
end of the PPP connection, but make sure to add separate routes four your
local network. And if you decided to let the rest of the machines out, there
default gateway should be the linux machine.
You should in any case register your office IP numbers, you see, the linux
machine will have no way of deciding where the send the data if there excists
machines with the same IP number both on the local network and across the PPP
line.

Well, the time is 09:30 right now here in sweeden. I am just about to leave,
for class and I'll be home again around 17, 18 a'clock (local time). You'll
probably be able to reach me by EMail during that time, otherwise feel free
to phone me before 23:00. My number is +46 46 130188.
