/sbin/iptables -A OUTPUT -o ppp0 -p tcp --dport 21 -m state --state
NEW,ESTABLISHED -j ACCEPT

/sbin/iptables -A INPUT -i ppp0 -p tcp  --sport 21 -m state --state
ESTABLISHED -j ACCEPT

/sbin/iptables -A OUTPUT -o ppp0 -p tcp --dport 20 -m state --state
NEW,ESTABLISHED -j ACCEPT

/sbin/iptables -A INPUT -i ppp0 -p tcp  --sport 20 -m state --state
ESTABLISHED,RELATED -j ACCEPT

/sbin/iptables -A OUTPUT -o ppp0 -p tcp --sport 1024:65535 --dport
1024:65535 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

/sbin/iptables -A INPUT -i ppp0 -p tcp --sport 1024:65535 --dport
1024:65535 -m state --state ESTABLISHED,RELATED -j ACCEPT

Each "double" line is in fact a single line.

Here, the range is not the one you want, but you can modify.

and, I insist, use man iptables, to fit exactly want you want, my
example, is for my use, this not perhaps what you want (input
connections are forbidden with these rules, only output and the answer
of a remote server is allowed).
