You're most welcome.

When you say "internal IP"... I hope you don't mean RFC1918
private address, because that won't work. The DNS server would
need to listen on a public address, or have some system listening
on a public address proxy requests to the "hidden" machine.
GS> That is were ns1.oakwood.surrey.org.uk is located.
ns1.oakwood-surrey.org.uk ?
FWIW, that system doesn't seem to be configured for reverse,
either. It's moot because your upstream hasn't delegated to you,
but there'd still be more config on your end.

Could be. I've not dealt with granitecanyon.

Possible.
GS> How difficult is this?
It's hard to say; much depends on your background. You'll need
wireless, DNS, networking, and routing clue... whether you hire
staff, use consultants, read everything you can, or a mixture is
up to you.
To get up and running right, I think it's fastest and cheapest to
hire experts. (Warning: I could be biased.) However, for the
long haul, it's better to be as self-sufficient as possible.
On what scale do you wish to create an ISP? How many customers?
How much bandwidth? IMHO, any serious operation _really_ needs
at least two separate upstreams and two separate border routers
for redundancy. Even if there were a turnkey guide on how to
configure this, you'd not want an inexperienced person running
the network.
GS> Finally can you recommend a good book that will cover the basics aswell
as
GS> the more complex.
I'll have to let someone else answer this. I've read a few
O'Reilly books dealing with specific topics, but personally have
done most of my learning by experimentation on test machines,
reading mailing lists, looking at source code, reading RFCs, et
cetera. It's also been over many, many years... I really don't
know of any "start a world-class ISP in four hours"-type books.
The venerable ISP metafaq is at:
http://www.amazing.com/internet/
although it looks like it's a bit on the dated side.
For wireless, I'd suggest the isp-wireless mailing list, which
one can find via
http://www.isp-planet.com/
I monitor a few of the isp-planet mailing lists, but often wonder
why... most of the clueful people seem to have given up on those
lists as a lost cause. The last I knew, however, isp-wireless
still had some good discussions.
