I just stick with all private addressing. The radios, high gain antennas and TenXs we use all do NAT in them, so we just leave it at that.

Makes figuring out who's CPE belongs to who's equipmnent much easier: For example: Customer addr = 64.123.105.33, CPE addr: 10.123.105.33 We keep out CPE private, and customer addr public, but we aren't quite THAT organized. pd Ryan Langseth wrote: >David, > >On Thu, 2006-11-09 at 11:23 -0600, David E.
