Internet sharing with ubuntu?

I have a Ubuntu Server with the internet comming straight into it from
the DSL modem. how do you share the internet with the rest of my
computers on my network using DCHP and with out using a proxy server?

You need to configure iptables for NAT (network address translation, or
IP masquerading). The Linux Networking Howto tells you how to do it.

You can use the package ipmasq to do it for you. Or you can use the
package shorewall to do a lot more besides with a nice GUI interface.

you can also use firestarter a firewall program that does NAT. as long
as you have 2 ethernet cards and a hub/switch. eth0 i-net, eth1 LAN
coneted to hub/switch. this very problem was what got me into linux
