Neither worked :(
"service nat restart" yields: "nat: unrecognized service"
enabling ipv4 forwarding doesnt seem to route the traffic.
Any other ideas?
That means you didn't use the K12LTSP distro that installs a lot of nice
stuff for you.
Below is the 'nat' init script. Change the PUBLIC_ETHERNET interface at
the top if needed and fix any wrapped lines.
#!/bin/sh

# Version: 0.0.3

# chkconfig: 2345 90 10
# description: Starts and stops Network Address Translation for 12Linux/LTS

PUBLIC_ETHERNET="eth1"
# Source function library.
. /etc/init.d/functions
start() {
echo -n "Starting up Network Address Translation: "
# Load the NAT module (this pulls in all the others).
modprobe iptable_nat
# In the NAT table (-t nat), Append a rule (-A) after routing
# (POSTROUTING) for all packets going out eth1 (-o eth1) which
says to
# MASQUERADE the connection (-j MASQUERADE).
iptables -t nat -A POSTROUTING -o $PUBLIC_ETHERNET -j MASQUERADE
# Turn on IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
echo
return 0
}
stop() {
echo -n "Stopping Network Address Translation: "
echo 0 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -D POSTROUTING -o $PUBLIC_ETHERNET -j MASQUERADE
echo
return 0
}
restart() {
stop
start
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart|reload)
restart
;;
*)
echo "*** Usage: nat {start|stop|restart}"
exit 1
