Subject: RE: NAT external/Public IP
It is stated that, "the main contention is that private addresses are
generally not considered routable on the public internet. I wouldn't hazard that
the RFC is always strictly followed as there have been cases where I've seen
private addresses being used (routed across a public interface)"
The issues is Should Not be Routed. First, they will not be blocked as a source on most routers, Next, it is amazing how
often they are routed. I remember working for an ISP a long while back that was threatened to be disconnected from the
Internet if they did not stop routing the 10.x range in their BGP tables (and this was an International ISP).
Further, finding source route paths over the Internet is not difficult. Thus it is possible to route "private" address
