Subject:   ipfw is making contact with 198.61.170.85 port 4021

A firewall should not be making its own contact with any public ip 
address. This is a security hole.

I have not played with ipfw since before it was rewritten to become 
ipfw2 so I do not know when this internal "call home"  function was 
added. pf and ipf are not doing this. I block it to be secure.

Can any one provide any info about this?
