Hi,
what  you're going  to do  is drop  every new  TCP connection  to your
interface ppp0.

What you want to to should be something like that

iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD DROP

iptables -A INPUT -s 127.0.0.1 -j ACCEPT
iptables -A OUTPUT -s 127.0.0.1 -j ACCEPT

iptables -A INPUT -s $MACHINE -j ACCEPT
iptables -A OUTPUT -s $MACHINE -j ACCEPT

$machine is your machine IP address.

regards
Frederic
