[SOLVED] Enquiry of Zimbra installation on NAT environment

[POla]

Assume internal IP is 172.50.110.123, public IP is 201.33.190.172 and domain is abc.com.my host by other. NAT is done at firewall.

/etc/hosts

127.0.0.1 localhost
172.50.110.123 mail.abc.com.my mail

If domain abc.com.my has an mx record mail.abc.com.my, can i have another host name rather than "mail"?

/etc/resolv.conf

search abc.com.my
nameserver 127.0.0.1
nameserver 202.188.0.133
nameserver 202.188.1.5

/etc/bind/named.conf.local

zone "mail.abc.com.my" {
type master;
file "/etc/bind/db.mail.abc.com.my";
};

zone "110.50.172.in-addr.arpa" {
type master;
file "/etc/bind/db.172";
};

Th zone should be abc.com.my or mail.abc.com.my?

/etc/bind/db.mail.abc.com.my

;
; BIND data file for local loopback interface
;
$TTL    604800
@       IN      SOA     mail.abc.com.my. root.abc.com.my. (
                              2         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;

@       IN      NS      mail.abc.com.my.
@       IN      A       172.50.110.123
mail    IN      A       172.50.110.123

What mean by @ stated above. The @ IN A 172.50.110.123 is needed?

/etc/bind/db.172

;
; BIND reverse data file for local loopback interface
;
$TTL    604800
@       IN      SOA     mail.abc.com.my. root.abc.com.my. (
                              2         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      mail.
154     IN      PTR     mail.abc.com.my.

Does the mail. represent the FQDN mail.abc.com.my?

I installed the zimbra already and it worked fine but I just wonder there is some wrong configuration. To install zimbra in NAT environment using config files above, anything wrong or can be impoved? May I know why the email is user@mail.abc.com.my and it work? Not that it should be user@abc.com.my? The MX record is abc.com.my IN MX 0 mail.abc.com.my; mail.abc.com.my IN A 201.33.190.172. I don't want to create another domain after installation. I think about change the domain name when come to "DNS ERROR resolving MX for mail.abc.com.my" installation step but with those config file I listed above, this step didn't appear until finish.

Your help can made me have better understanding, thank you.

Sorry, I'm not fully following your setup, but I can tell you that typically in a NAT environment you are going to have to setup Split DNS in order to get things working properly. There is a wiki page that describes this setup. Also, as far as the user@mail.abc.com.my versus user@abc.com.my when you install Zimbra I believe it defaults to using the full host name as the email domain. You need to go into the configuration during the install process and specify that you want the domain to be "abc.com.my".

Thank you for giving the idea.
