DHCP Server parameters for Ethernet n
Secondary DNS Server
The IP address of a secondary DNS server (if available) to be used by DHCP clients on the LAN.
Domain Name
The domain name that will be returned to clients.
Lease Duration d days h hrs m mins
How long a DHCP client can use the assigned IP address before it must renew its configuration
with the DHCP server. When configuring this value using the command line interface be aware
that this parameter is specified in minutes. The three boxes here are for convenience when
using long lease durations.
Wait for s milliseconds before sending DHCP offer reply
When the checkbox box is enabled, the router will use the value in the text box as the delay to
use prior to sending out the DHCP_OFFER message. Enabling this functionality and setting the
delay to a non-zero value will allow other DHCP servers on the network to respond first.
Only send offers to Wi-Fi clients
When enabled, causes the router to only send DHCP offers to Wi-Fi clients. This is useful if the
router is being used as an access point and there is a separate DHCP server on the Ethernet
LAN.
DHCP Relay
Forward DHCP requests to a.b.c.d
The values in these two text boxes specify the IP addresses of the two supported DHCP relay
agents. If the DHCP server is on a different subnet, specifying the IP address of the server in
this text box will cause the router to forward DHCP requests to the IP address specified. The
DHCP server must be within 4 hops.
