[DHCP Server]
The DHCP Server gives out IP addresses when a device is booting up and request an IP to be logged on
to the network. That device must be set as a DHCP client to obtain the IP address automatically. By
default, the DHCP Server is enabled. The DHCP address pool contains the range of the IP address that
will automatically be assigned to the client on the network.
Starting IP address: The starting IP address for the DHCP server’s IP assignment.
IP Pool Count: The max user pool size.
Lease Time: The length of time for the IP lease.
[DHCP Relay]
A DHCP relay is a computer that forwards DHCP data between computers that request IP addresses and
the DHCP server that assigns the addresses. Each of the device’s interfaces can be configured as a
DHCP relay. If it is enable, the DHCP requests from local PCs will forward to the DHCP server runs on
WAN side. To have this function working properly, please run on router mode only, disable the DHCP
server on the LAN port, and make sure the routing table has the correct routing entry.
DHCP Server IP for relay agent: The DHCP server IP Address runs on WAN side.
[DNS Relay]
The DNS Configuration allows the user to set the configuration of DNS.
DNS Rely Selection: If user wants to disable this feature, he just needs to set both Primary & Secondary
DNS to 0.0.0.0. Using DNS relay, users can setup DNS server IP to 192.168.2.1 on their computer. If not,
device will perform as NO DNS relay.
