To the ipfw/natd gurus. The following is from man natd. -punch_fw basenumber:count This option directs natd to ``punch holes'' in an ipfirewall(4) based firewall for FTP/IRC DCC connections. This is done dynamically by installing temporary firewall rules which allow a particular connection (and only that con nection) to go through the firewall. The rules are removed once the corresponding connection terminates. A maximum of count rules starting from the rule number basenumber will be used for punching firewall holes. The range will be cleared for all rules on startup. As you can see this does not tell you how to use it or what the values for basenumber and count is suppose to represent. Can someone explain how to code this natd option, where it goes, and what or how it interacts with the ipfw rules for FTP ports 20 & 21?
