Title: Custom DNS Forwarding
Post by: CH Cheah on July 16, 2004, 08:02:15 PM: Anyone know how to define custom settings for forwarding certain DNS queries to other DNS servers.

For example when I intend to use a local DNS server for the local domain (the other DNS queries will be forwarded to the Internet directly)

Post by: CH Cheah on July 18, 2004, 05:04:02 PM: SME box is set as the DNS server but some of the clients need to access another private network which has it's own DNS server. Thus I would like to forward all queries for this private network to their DNS server.

A good example would be WinRoute's (Kerio) custom forwarding option. It allows you to define which DNS server to query based on domain name.

Any ideas ?

How do I tell my cache to consult internal DNS servers? Our network has internal servers at IP addresses 10.1.2.5 and 10.1.2.6 providing information about the moon.af.mil and 10.in-addr.arpa domains.

Answer: Put

10.1.2.5
10.1.2.6

into /service/dnscache/root/servers/moon.af.mil and into /service/dnscache/root/servers/10.in-addr.arpa. Make sure that both files are readable by the DNS cache account. Restart dnscache:

svc -t /service/dnscache

dnscache will contact the internal servers for information about moon.af.mil and 10.in-addr.arpa. If the moon.af.mil servers delegate darkside.moon.af.mil to another server, dnscache will contact that server for information about darkside.moon.af.mil.
