So does that mean that if I take down my firewall (i.e. my security policy), you'll be able to ping my servers whose addresses are NATted??? Let me propose a new question.... If there is a means for all hosts to have addresses that are reachable from all other hosts (barring that a security policy is in place), will companies renumber their internal networks to coincide with this addressing scheme? If we (the Internet community) used private addresses and NAT for all hosts that do not want/need/require access from the Internet, would the addressing problem be as much of a problem as it appears to be? If we are as generous with the IPv6 addresses, how soon before we have the same address problem? Charles
