Chapter 4: Software Configuration
Starting IP Address: Enter the starting IP address for the DHCP server's IP assignment. Because
the default IP address for the Router is 192.168.1.1, the default Start IP Address is 192.168.1.2,
and the Start IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.254.
IP Pool Count: The max user pool size.
Lease Time: The length of time for the IP lease. After the dynamic IP address has expired, the
user will be automatically assigned a new dynamic IP address. The default is 259200 seconds.
DNS Relay: If you want to disable this feature, you just need to set both Primary and secondary
DNS IP to 0.0.0.0. If you want to use DNS relay, you can setup DNS server IP to 192.168.1.1 on
their computer.
If not, the device will perform as no DNS relay.
Primary DNS Server: Type in your preferred DNS server.
Secondary DNS Server: Type in your secondary DNS server.
Current Pool Summary: Click this button, you can view the IP addresses that the DHCP Server
gives out.
Note: If Automatically is selected in DNS Relay, this router will accept the first received DNS
assignment from one of the PPPoA, PPPoE or MER/DHCP enabled PVC(s) during the connection
establishment. If Manually is selected in DNS Relay, it is necessary for you to enter the primary
and optional secondary DNS server IP addresses. After typing in the address, click SAVE button
to save it and invoke it.
DHCP Relay: Select Relay, the Router will work as a 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
enabled, 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: Enter the DHCP server IP Address runs on WAN side.
Note: If you select Disabled, the DHCP function will not take effect. DHCP Relay may be no use if
default route is not dynamic or static routing mode.
