If end-to-end connectivity is your idea of "the Internet", then a firewall's primary purpose is to break the Internet. It's how we provide access control. If a firewall blocks "legitimate, authorized" access then perhaps it adds to breakage (PMTU, ICMP, other blocking) but otherwise it works. As to address the other argument in this threat on NAT / private addressing, PCI requirement 1.3.8 pretty much requires RFC1918 addressing of the computers in scope... has anyone hinted at PCI for IPv6?
