[NTLUG:Discuss] Sharing Internet Connection

[Dan Carlson]

Start with the masquerade howto:

http://www.linuxdocs.org/HOWTOs/IP-Masquerade-HOWTO.html

The details will vary depending on whether you are running a 2.2 or 2.4
kernel and whether you are using ipchains or iptables.

I am running a 2.4 kernel with ipchains.  All it takes to masquerade my
local network is the following ipchains rule:

-A forward -s 192.168.1.0/24 -d 0/0 -j MASQ

In order for this to work, you do need to have ip forwarding turned on in
the kernel:

echo 1 >/proc/sys/net/ipv4/ip_forward

And the clients on your local network have to specify your server as their
gateway in their tcp/ip configurations.
