Having thought about it, I haven't tried it yet, would the above work?
Doesn't '!+internal_hosts' expand to:
! 141.163.0.0/16 : ! 127.0.0.0/8 : * (note the implied ':*')
If so, then I'm in the same situation whereby the ISP is not seen because
of the '*'. If not, then (I assume) negated named lists do not have an
implied ':*' on the end?
