  Why would anyone want all internal machines public anyway ?

  Historically, we used nat for 2 purposes:

    (1) to shield inside machines
    (2) free up ipv4 (was an accidental consequence of (1)

 I need to read about ipv6 - but can I keep (1) with ipv6 ? i.e.
machines inside access to internet similar to what they have now via
firewall/nat ... but no way for those ipv6 addresses to be seen SYN'd
from outside.
