answer....
Make a file called /etc/rc.d/rc.masq and in it put:
#!/bin/sh
/sbin/depmod -a
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -i ppp0 -j MASQ
then make it executable thusly:
chmod 777 rc.masq
then add to your /etc/rc.d/rc.local:
/etc/rc.d/rc.masq
then run the rc.masq script.
Thane make sure your other computers have their gateway correctly as your
gateway machines ip address. Violla.
