Simple iptables question

When following a step by step guide for setting up Azureus it gave an instruction to open udp port 6972 using the command below.

/sbin/iptables -I INPUT -p udp --destination-port 6972:6972 -j ACCEPT

If i wanted to reverse this how would i go about it.

Note: I have no clue about iptables but do plan to get one soon!

Stephen.

/sbin/iptables -I INPUT -p udp --destination-port 6972:6972 -j DROP

Is that what you're looking for?

Yes. ACCEPT accepts packets. DROP drops them. I wrote a small piece on iptables. here
