Linux DNS Configuration

Hello,

I'm trying to configure a Linux server to act as a DNS server. Below is
my config files:

File: "/etc/named.conf"

zone "my-domain.com" {
type master;
file "/var/lib/named/my-domain.com.hosts";
allow-transfer { Slave Server; };
};
zone "XXX.XX.XX.in-addr.arpa" {
type master;
file "/var/lib/named/XXX.XX.XX.in-addr.arpa";
};

File: "/var/lib/named/my-domain.com.hosts"

$ttl 38400
my-domain.com. IN SOA my-domain.com. admin.my-domain.com.
(
2006041804
10800
3600
604800
38400 )
my-domain.com. IN NS ns1.my-domain.com.
my-domain.com IN NS ns2.my-domain.com.
my-domain.com. IN A MyServerIP

mail.my-domain.com. IN CNAME my-domain.com.
my-domain.com. IN MX 10 mail.my-domain.com.
www IN CNAME my-domain.com.
ftp IN A MyServerIP
ns1 IN A MyServerIP
ns2 IN A SlaveServerIP

File: "var/lib/named/XXX.XX.XX.in-addr.arpa"

$ttl 38400
my-domain.com. IN SOA my-domain.com. admin.my-domain.com.
(
2006041804
10800
3600
604800
38400 )

my-domain.com. IN NS ns1.my-domain.com.

XX PTR ns1.my-domain.com

BIND is running on the server. If I use dig, host & ping from the local
server all information returns correctly.

>From an external machine I can't ping ns1.my-domain.com.

Am I doing something wrong?

Please advice.

Thanks

Don't you want to add the ftp record here too?

Are the external machine setup to use your dns system?
Could there be a firewall blocking port 53 request from the external
machines?
