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?
