Comments in IPTables Rules

To make an iptables rule with a comment, simply add on the following arguments to the rule:

-m comment --comment "limit ssh access"
Depending on your distribution, you may need to load the ipt_comment or xt_comment modules into your running kernel first.

A full iptables rule to limit ssh access would look something like this:

iptables -A INPUT -j DROP -p tcp --dport 22 -m comment --comment "limit ssh access"

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
