IP Address
Type the IP address of your NBG6604 in dotted decimal notation.
IP Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your NBG6604 will
automatically calculate the subnet mask based on the IP address that you assign. Unless
you are implementing subnetting, use the subnet mask computed by the NBG6604.
DHCP Server
Select
Ena b le
to activate DHCP for LAN.
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (computers) to obtain TCP/IP configuration at startup from a server.
Enable the DHCP server unless your ISP instructs you to do otherwise. Select
Disa b le
to stop
the NBG6604 acting as a DHCP server. When configured as a server, the
NBG6604 provides TCP/IP configuration for the clients. If not, DHCP service is
disabled and you must have another DHCP server on your LAN, or else the computers
must be manually configured. When set as a server, fill in the following four fields.
IP Pool Starting
Address
This field specifies the first of the contiguous addresses in the IP address pool for LAN.
Pool Size
This field specifies the size, or count of the IP address pool for LAN.
Lease Time
Specify for how many hours each DHCP client device can use the DHCP information
(especially the IP address) before it has to request the information again.
