Why on earth would anyone let any of the following networks in to their
network at the border?
10.0.0.0/8
172.16.0.0/12
192.168.0.0/16
Hell, for that matter, I block anything claiming to be from our networks as
well. There's no way they'll be originating from the outside unless it's
spoofed.
Nothing and I mean NOTHING claiming to be from any of them at your border
is valid.
