Afaik, the only two rules you'll need are to allow incoming traffic using
protocol
number 47, as well as TCP port 1723. If you're restricting outbound
traffic, add
outgoing rules as well.
iptables -A INPUT -j ACCEPT -i ethX --proto 47
iptables -A INPUT -j ACCEPT -i ethX -p tcp --dport 1723
Hope that helps. The -i ethX is optional -- it allows traffic only on that
interface.
