Hi. I have unbound as proxy for a private zone DNS server. This server holds some 10.0.x addresses. Unbound works nice but it won't resolve reverse lookups. nslookup queries. I've read unbound.conf manpage and I think there is a part about my problem but I've been unable to solve it. I'm not sure how can I tell unbound to treat is as nodefault. I a zone for my domain, this works, but won't do reverse. local-zone: "private.domain.name" redirect local-data: "private.domain A private.dns.server" But how I tell unbound to resolve reverse ? I tried many many many things but I didn't solve it. I tried adding a nodefault like this: local-zone: "private.domain.name" nodefault with the number: local-zone: "10.0." nodefault or like this: local-zone: "10.0" nodefault or this: local-zone: "10.in-addr.arpa." static local-zone: "10.in-addr.arpa. 10800 IN NS localhost." local-data: "10.in-addr.arpa. 10800 IN SOA private.dns.server" please someone give me a hint. Thank you.
