This was only tested with Slackware, but should work on almost every other distribution and even for Windows.
Assume this is your setup:
A --> B --> Internet
You want to connect A to the internet, B is already connected.
Run this
Code:
if [ -f /proc/sys/net/ipv4/ip_forward ]; then
echo "Activating IPv4 packet forwarding."
echo 1 > /proc/sys/net/ipv4/ip_forward
fi
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
on B as root and this
Code:
route add default gw $(ipadresse of B)
on A.
Done. Isn't it great?
You could setup a DHCP daemon on B to automate some things, but there are other HOWTOs for that.
