you need to create 2 files for 2 domains represented by both the nic cards in /etc/named.conf..it would look something like this:
zone "x.domain.com" IN {
type master;
file "xdom.com";
};
zone "y.domain.com" IN {
type master;
file "ydom.com";
}
zone "3.28.10.in-addr.arpa" IN {
type master;
file "10.28.3";
};
zone "4.28.10.in-addr.arpa" IN {
type master;
file "10.28.4";
};
and create xdom.com and ydom.com and 10.28.3 and 10.28.4 and then define the ip addresses of all machines on the either subnets in the corresponding files.you can also define the ip address of the ftp,www server with an MX record to the mail server...any problem understanding me..let me know by mail
