If you could really proxy everything, you'd be able to use 10/8
everywhere and never hit problems, even if two private peers overlap
in usage within 10/8.
I can assure you that the "proxy everything" statement breaks down
with every enterprise-to-enterprise interconnection project I've run
into. There are some protocols that are just not meant to do that.
