Configuring DHCP servers
Mask
The subnet mask on the network to which the router is connected.
Gateway
A gateway is required in order to route data to IP addresses that are not on the local subnet.
The value in this text box specifies the IP address of the gateway (which is usually the IP
address of the router itself as configured by the IP address of the Ethernet interface
associated with this DHCP instance). Alternatively, this may be set to the IP address of another
router on the LAN.
DNS Server
The IP address of the primary DNS server to use by clients on the LAN. This is usually the IP
address of the route itself. Alternatively, this may be set to the IP address of an alternative
DNS server on the LAN.
Secondary DNS Server
The IP address of a secondary DNS server (if available) that DHCP clients on the LAN use.
Domain Name
The domain name 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 this setting is enabled, the router uses 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.
Duplicate Address Detection
If enabled, causes the router to detect duplicate addresses.
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 serves 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.
