If you already have the two machines networked together, all you have to
do is to implement a script using IPTABLES - it's really easy - you
DON'T have to have two NIC's or anything stupendous like that - and the
following is a script that I currently use for doing my "sharing":
----------------------------------------------------------
#!/bin/sh
# Begin of /usr/bin/start_ics
source /etc/init.d/functions
case "$1" in
start)
echo "Enabling masquerading..."
echo "1" > /proc/sys/net/ipv4/ip_forward
# evaluate_retval
echo -n "Bringing up iptables..."
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
;;
stop)
echo -n "Disabling masquerading..."
echo "0" > /proc/sys/net/ipv4/ip_forward
evaluate_retval
echo -n "stopping iptables ... "
iptables -t nat -F
evaluate_retval
;;
restart)
$0 stop
/usr/bin/sleep 1
$0 start
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
;;
esac
# End of /usr/bin/start_ics
----------------------------------------------------------
...so you can use it like "start_ics start" - works like a charm mate.
