Thank you for all your replies!
I'll try to implement your suggestions using a subdomain.
Best regards.

Oggetto: Re: Define an internal zone with only a couple of A records, then
forward to an external dns server
If you load the zone your server will believe it knows everything about the
zone and not forward anything below it.
If you load foo.com with two records, nothing but those two records will ever
resolve on that server for foo.com .
One way to make it work would be to load two zones. Vpn1.foo.com and
vpn2.foo.com each with their A records. Then you would only blackhole things
below vpn1.foo.com and vpn2.foo.com .

Hi all,
I googled all the morning without success :( I'm using Bind 9.9.1 and i'm a
newbie of Bind. This is my goal:
- I want to define in my dns server a zone " external_partner.com ", which is
the domain of our partner who manages it with his dns public server "
dns.external_partner.com ".
- I need to define into this zone a couple of servers ("vpn_host_1.
external_partner.com ", " vpn_host_2. external_partner.com ") because we
connect via vpn to our partner.
- I want that the rest of the names, e.g. " www.external_partner.com ", are
resolved forwarding the requests to the dns of our partner.
I tried this without success:
- in "named.conf":
zone " external_partner.com " { type master; file "master/ external_partner.com
.zon"; forwarders {xxx.xxx.xxx.xxx;}; };
and I have "recursion yes" in the options.
- in " external_partner.com .zon" I have only the two entries:
$TTL 300
@ IN SOA dns.edistar.com . admin.dns.edistar.com . (
2013011701 ; Serial
300 ; Refresh
300 ; Retry every hour
300 ; Expire after a week
300 ) ; Minimum ttl of 1 day
IN NS dns.edistar.com .
TXT "vpn servers"
vpn_host_1. external_partner.com . IN A xxx.xxx.xxx.xxx
vpn_host_2. external_partner.com . IN A xxx.xxx.xxx.xxx
I read about "forward first" option but is the opposite of my goal, correct?
Thanks in advance for your responses.
