DESCRIPTION
To change an entry's position in the numbered list, select the method and click Move to
display a field to type a number for where you want to put it and press [ENTER] to move
the rule to the number that you typed.
This is the index number of the domain zone forwarder record. The ordering of your rules
is important as rules are applied in sequence.
A hyphen (-) displays for the default domain zone forwarder record. The default record is
not configurable. The NXC uses this default record if the domain zone that needs to be
resolved does not match any of the other domain zone forwarder records.
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.
A "*" means all domain zones.
This displays whether the DNS server IP address is assigned by the ISP dynamically
through a specified interface or configured manually (User-Defined).
This is the IP address of a DNS server. This field displays N/A if you have the NXC get a
DNS server IP address from the ISP dynamically but the specified interface is not active.
This is the interface through which the NXC sends DNS queries to the entry's DNS server.
A MX (Mail eXchange) record identifies a mail server that handles the mail for a particular
domain.
Click this to create a new entry.
Double-click an entry or select it and click Edit to be able to modify the entry's settings.
To remove an entry, select it and click Remove. The NXC confirms you want to remove it
before doing so. Note that subsequent entries move up by one when you take this action.
This is the index number of the MX record.
This is the domain name where the mail is destined for.
This is the IP address or Fully-Qualified Domain Name (FQDN) of a mail server that
handles the mail for the domain specified in the field above.
This specifies from which computers and zones you can send DNS queries to the NXC.
Click this to create a new entry. Select an entry and click Add to create a new entry after
the selected entry.
Double-click an entry or select it and click Edit to be able to modify the entry's settings.
To remove an entry, select it and click Remove. The NXC confirms you want to remove it
before doing so. Note that subsequent entries move up by one when you take this action.
To change an entry's position in the numbered list, select the method and click Move to
display a field to type a number for where you want to put it and press [ENTER] to move
the rule to the number that you typed.
This the index number of the service control rule. The ordering of your rules is important
as rules are applied in sequence.
The entry with a hyphen (-) instead of a number is the NXC's (non-configurable) default
policy. The NXC applies this to traffic that does not match any other configured rule. It is
not an editable rule. To apply other behavior, configure a rule that traffic will match so the
NXC will not have to use the default policy.
This is the zone on the NXC the user is allowed or denied to access.
This is the object name of the IP address(es) with which the computer is allowed or
denied to send DNS queries.
This displays whether the NXC accepts DNS queries from the computer with the IP
address specified above through the specified zone (Accept) or discards them (Deny).
