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.
Server and Relay Off 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.
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.
