Tricky DNS configuration. Help!

I dunno ... can you delegate away domain names you're not auth for?  I thought
if you were auth for plop.com you can only delegate away subs for that, like
titi.plop.com, toto.plop.com.  You can't delegate away the entire domain 
you're auth for.

This setup aside, you want F1 & F2 to query G as well as the ISP DNS, right?
I would set up specific forward zones for everything G is auth for, and a
general forward statement with ISP DNS as forwarder.  If you're interested
in everything in G's cache as well, you can chain it like
F1 & F2 -> G -> ISP DNS.

Sparc Ultra5 256MB works for me.  Not that I'm biased or anything.  And
BIND comes bundled with the OS, but you have to patch it.
