NAT and PAT are not inherently strong security measures, regardless of the
mappings. At best, it will function as a sort of security through
obscurity. The real purpose of {N,P}AT is to conserve IP address space
and/or translate for non-routable (e.g. RFC 1918) networks.

    - Charter Communications: Mislead their customers about service
      levels, block normal Internet connectivity, and exhibit excessive
      downtime.
    - AT&T: Honoring the "checks" they send out to entice you to switch
      long-distance providers is apparently optional.
    - eFax: Receive (not send) 20 pages of *unsolicited* faxes, and lose
      your account.
