local domains

[Oliver Vecernik]

Hi,

www.mydomain.com and mail.mydomain.com are maintained from my ISP. My
private network is behind a router with NAT and I set up BIND 9.2.5
(FC3) with intra.net as domain name. Everthing works as expected.

My question is if it's possible to name my private lan also with my
official domain (e.g. mydomain.com)? Internal users should look up my
DNS and external ones use the DNS from my ISP. But this doesn't work for
www and mail from inside at the moment. Here is my configuration:

# cat /etc/named.conf
options {
        directory "/var/named";
        forwarders {
                195.3.95.68;
                213.33.98.136;
        };
        query-source port 53;
};

zone "." {
  type hint;
  file "named.ca";
};

zone "mydomain.com" {
  type master;
  file "mydomain.com.zone";
};

zone "0.168.192.in-addr.arpa" {
  type master;
  file "0.168.192.in-addr.arpa";
};

# cat /var/named/mydomain.com.zone
$TTL 86400
@       IN      SOA     p500.mydomain.com. root.mydomain.com. (
                        2005031812      ; serial
                        300             ; refresh after 5 minutes
                        60              ; retry after 1 minute
                        1209600         ; expire after 2 weeks
                        43200 )         ; minimum TTL of a half day

        IN      NS      p500.mydomain.com.

        IN      MX      5       p500.mydomain.com.

                IN      A       192.168.0.3

wgt624          IN      A       192.168.0.1
p500            IN      A       192.168.0.3
oj              IN      A       192.168.0.5
lanmodem        IN      A       192.168.254.1
www             IN      A       81.223.238.230 ; does not work!

mail            IN      CNAME   p500
pop             IN      CNAME   p500
imap            IN      CNAME   p500
router          IN      CNAME   wgt624

# cat /var/named/0.168.192.in-addr.arpa
$TTL 86400
@ IN SOA p500.mydomain.com. root.mydomain.com. (
  2005031808 ; serial number
  300        ; refresh
  60         ; retry
  1209600    ; expire
  43200      ; minimum TTL for negative answers
)
        IN NS   p500.mydomain.com.

 1      IN PTR  wgt624.mydomain.com.
 3      IN PTR  p500.mydomain.com.
 5      IN PTR  oj.mydomain.com.

Is this possible?

Oliver.
