39.6.8
MX Record
A MX (Mail eXchange) record indicates which host is responsible for the mail for a particular
domain, that is, controls where mail is sent for that domain. If you do not configure proper MX
records for your domain or other domain, external e-mail from other mail servers will not be able to
be delivered to your mail server and vice versa. Each host or domain can have only one MX record,
that is, one domain is mapping to one host.

LABEL
DESCRIPTION
Domain Zone
A domain zone is a fully qualified domain name without the host. For example,
zyxel.com.tw is the domain zone for the www.zyxel.com.tw fully qualified domain name.
For example, whenever the UAG receives needs to resolve a zyxel.com.tw domain name,
it can send a query to the recorded name server IP address.
Enter * if all domain zones are served by the specified DNS server(s).
DNS Server
Select
DNS Server(s) from ISP
if your ISP dynamically assigns DNS server information.
You also need to select an interface through which the ISP provides the DNS server IP
address(es). The interface should be activated and set to be a DHCP client. The fields
below display the (read-only) DNS server IP address(es) that the ISP assigns.
N/A
displays for any DNS server IP address fields for which the ISP does not assign an IP
address.
Select
Public DNS Server
if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field to the right. The UAG must be able to connect to the DNS
server without using a VPN tunnel. The DNS server could be on the Internet or one of the
UAG’s local networks. You cannot use 0.0.0.0. Use the
Query via
field to select the
interface through which the UAG sends DNS queries to a DNS server.
Select
Private DNS Server
if you have the IP address of a DNS server to which the UAG
connects through a VPN tunnel. Enter the DNS server's IP address in the field to the right.
You cannot use 0.0.0.0.
