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

# NOTE: This is an example for an internal Network address of
# 192.168.0.x The sub netmask is 255.255.255.0 or "24" bit
# Please change this if you use different internal IP addresses.

/sbin/ipchains -P forward DENY
ipchains -A forward -i ppp0 -j MASQ
/sbin/ipchains -A forward -s 192.116.0.0/24 -j MASQ

You have to change the "192.116.0.0/24" regarding to your addresses and
configurations.
Then all you have to do is type: /etc/rc.d/init.d/./ipmasq
and this should work.


If you're using 2.4 kernel and NetFilter, here is the way how running
IP-masq with iptables:


iptables -P FORWARD ACCEPT 
iptables -A FORWARD -i ppp0 -m state --state NEW,INVALID -j REJECT 
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE 
echo 1 > /proc/sys/net/ipv4/ip_forward
