DHCP Server Scope 1
Start IP Address / End IP
Address
A range of IP addresses that are built in DHCP server will be assigned to clients.
Note: please change the Management IP Address List accordingly (at
System
Configuration >> System Information >> Management IP Address List
) to permit the
administrator to access the WHG CONTROLLER admin page after the default IP
address of the network interface is changed.
Preferred DNS Server
The primary DNS server that is used by this Service Zone.
Alternate DNS Server
The substitute DNS server that is used by this Service Zone.
Domain Name
Enter the domain name for this service zone.
WINS Server
The IP address of the WINS (Windows Internet Naming Service) server that if WINS
server is applicable to this service zone.
Lease Time
This is the time period that the IP addresses issued from the DHCP server are valid
and available.
Disregard Client Name
When enabled the system will not record the name of the device requesting for an IP
address. On the other hand, when disabled is selected, the system will record the
device’s name when issuing IP addresses. The devices name (Host Name) can be
seen under
DHCP Lease
tab.
DHCP Server Scope 2
Enable/Disable
When Enabled, an additional DHCP server can be configured to assign IP address to
clients associated to the alias IP of this Service Zone. The configurable fields are the
same as DHCP Server Scope 1.
Reserved IP Address List:
Each service zone can reserve specific IP addresses from predefined DHCP
range to prevent the system from issuing these IP addresses to downstream clients. Click the
Configure
button to edit the Reserved IP List.
The administrator can reserve a list of specific IP addresses for special device with certain MAC address.
Fill a set of IP address and MAC address as reserve, additional information can be entered in the
Description field. Click
Apply
to activate your settings.
DHCP Lease Protection:
When “Enabled”, whenever the Service Zone’s built-in DHCP server receives
a DHCP request, it will automatically bind the MAC address with an IP address permanently. This means
that once all the IP addresses have been assigned, it will be bound with the MAC address that first
acquired this IP. Subsequent devices with new MAC address will be unable to acquire an IP address.
When “Disabled” DHCP server will operate as usual, assigning available IP addresses upon DHCP
request.
