Re: DNS for internal end external

[Stephen Samuel <samuel@bcgreen.com>]

It looks like the views would do what's wanted, but you will
have to have two files... one for internal one for external.

If what you want to do is avoid having two files for machines
which have the same address for both external and internal,
then you can actually have three files:

One file is for unique internal addresses
one file is for unique external addresses
One file is for machines which have the same address {ex,in}ternally.

The third file would be included from inside each of the first two.

If what you actually want is to have one file with addresses for
both internal and external, then you'll have to put together a
filter...

For this, I'm thinking of something like:

# hostname	internal	external
www	A	192.168.45.11	37.45.222.11
ftp	A	192.168.45.51	37.45.222.51
mail	MX`1	intmail		extmail
mail 	MX 3	.		remote.mx.com.
intservice A	192.168.45.51	/

A quick perl or aqk  script would do a good job of
Tturning this into two separate files.
(left as an exercise for the reader... or you can
pay me to do it..:-)

intonly.me.com	192.168.53.31	.

A quick awk or perl script would go from this to a real zone file.
