LAN Settings 39
This page includes the following settings:
IP Address
The IPv4 address of the router for the default VLAN.
Subnet Mask
Only change the subnet mask if you have a specific reason to do so.
Enable DHCP Server
The Dynamic Host Configuration Protocol (DHCP) server feature automatically assigns IP
addresses to each computer on a VLAN. The DHCP server can be turned off if necessary.
Turning off the DHCP server requires you to manually set static IP addresses for each computer
on the VLAN.
IP Pool Starting/Ending Address
The IP pool is the range of IP addresses set aside for dynamic assignment to the computers on
the VLAN. The default range is 2 to 254 (253 computers). You can enter new starting and
ending IP addresses for the VLAN IP pool, or click
Auto IP Range
to automatically set a valid
range of addresses.
Lease Time
The length of time the DHCP server reserves an IP address for each computer on the VLAN.
VLAN ID
The ID number for the default VLAN. The default VLAN ID is 1. For more information on
configuring VLANs, see
“VLAN settings” on page 41 .
DHCP relay
Dynamic Host Configuration Protocol (DHCP) can dynamically allocate IP addresses and other
configuration information to network clients that broadcast a request. To receive broadcast
requests, a DHCP server would normally have to be in the same broadcast domain (VLAN) as
the clients. However, when the router's DHCP relay feature is enabled, the received client
requests can be forwarded directly by the router to a specified DHCP server on another
broadcast domain (VLAN). Responses from the DHCP server are returned to the router, which
then broadcasts them back to clients.
