[wellylug] Proxies under Linux RedHat 7.3

[Andrew Kemmy]

To further confuse the issue a proxy isn't strictly necessary to enable
a computer on a LAN to access the internet through a Linux machine.

Assuming you have a Linux computer with an internet connection, be it
dial-up, ADSL, etc, you can enable that computer to act as a gateway
for the other machines if they are all part of the same network.

Assuming it's a dial-up conection, the Linux computer will have two
interfaces: ppp0 for the dial-up, and eth0 for the LAN. You need to
enable packet-forwarding between these two interfaces, and you need to
make sure that the ip addresses on the LAN are "private" or reserved
addresses e.g. 192.168.x.x. Then it's as simple as making sure that the
linux box knows that it's default route is through ppp0, and that the
other computers on the LAN know that their default route is the ip
address associated with eth0 on the gateway computer. The next stage is
to make sure that DNS resolution is configured correctly on all
computers.

Documents that explain all much better than I can are at :

Hope this helps,

Andrew.
