Enable DHCP Relay
Server and Relay Off
Assign ISP DNS, SNTP
When you enable the DHCP server, the router dynamically assigns IP addresses to
computers in the local network. The router provides its own LAN IP address (192.168.1.1)
as both the gateway and the DNS server.
The router has a choice of advertising its own IP address (192.168.1.1) as the DNS server
or providing the DNS that was received from the WAN. This can be configured by
enabling/disabling Assign ISP DNS SNTP on the LAN Group Configuration page.
Note: ISP DNS, SNTP only applies when the DHCP server is enabled on the LAN Group
Configuration page.

of the Lease Time, the lease is either renewed or the
DHCP server issues a new IP. The amount of time is in
units of seconds. The default value is 3600 seconds (1
hour). The maximum value is 999999 seconds
(About 278 hours).
In addition to the DHCP server feature, the router
supports the DHCP relay function. When the router is
configured as DHCP server, it assigns the IP addresses to
the LAN clients. When the gateway is configured as
DHCP relay, it is responsible for forwarding the requests
and responses negotiated between the DHCP clients and
the server.
Relay IP The IP address of the DHCP relay server.
When the DHCP server and relay functions are turned
off, the network administrator must carefully configure
the IP address, Subnet Mask, and DNS settings of every
host on your network. Do not assign the same IP address
to more than one host. Also, your router must reside on
the same subnet as all the other hosts.
