How to forward all DNS queries through ISP DNS server ?
 
Hello everyone,

I would like configure a DNS server on Debian, only to forward through my ISP DNS servers.

I added on /etc/bind/named.conf

Quote:
fowarders (
<IP ISP server 1>
<IP ISP server 2>
);
and on /etc/bind/db.root

Quote:
. 3600000 IN NS ns1.isp.tld
ns1.isp.tld. 3600000 A <IP ISP server 1>
. 3600000 IN NS ns2.isp.tld
ns2.isp.tld. 3600000 A <IP ISP server 2>
Since, bind doesn't want start anymore.

Quote:
/etc/init.d/bind9 start
Starting domain name service...: bind9 failed!
Is someone has a solution or a better method?

Thanks.

sounds like you want a standard forwarding only service - http://www.zytrax.com/books/dns/ch6/#caching

Code:
fowarders (
<IP ISP server 1>
<IP ISP server 2>
);
;)
Code:
fowarders {
<IP ISP server 1>
<IP ISP server 2>
};

Thanks. I modified the code but bind still doesn't start.

I fixed the problem for bind9 lauching. There was a syntax error in named.conf file.
My DNS server forward correctly queries through my ISP DNS servers.

Now, I would like forward some queries to another local zone. Actually, it is my Active Directoy server.

I added in named.conf file:

Quote:
zone "mydomain.lan" IN {
type forward;
forwarders {<ip-server-on-mydomain>;};
};
and /etc/host file:

Quote:
192.168.0.200 mydomain server-on-mydomain mydomain.lan
The redirection seems work in local but not through a station using my DNS server.

Any ideas?

Thanks.
