The following table describes the fields in this screen.
Table 48 Network Setting > Home Networking > LAN Setup
LABEL DESCRIPTION
Interface Group
Group Name Select the interface group that you want to configure its LAN settings.
LAN IP Setup
IP Address Enter the LAN IP address you want to assign to your Zyxel Device in dotted decimal notation,
for example, 192.168.1.1 (factory default).
Subnet Mask Enter the subnet mask of your network in dotted decimal notation, for example
255.255.255.0 (factory default). Your Zyxel Device automatically computes the subnet mask
based on the IP address you enter, so do not change this field unless you are instructed to
do so.
DHCP Server State
DHCP Select Enable to have your Zyxel Device assign IP addresses, an IP default gateway and DNS
servers to LAN computers and other devices that are DHCP clients.
If you select Disable, you need to manually configure the IP addresses of the computers and
other devices on your LAN.
If you select DHCP Relay, the Zyxel Device acts as a surrogate DHCP server and relays DHCP
requests and responses between the remote server and the clients.
IP Addressing Values
The IP Addressing Values fields appear only when you select Enable in the DHCP field.
Beginning IP
Address
This field specifies the first of the contiguous addresses in the IP address pool.
Ending IP Address This field specifies the last of the contiguous addresses in the IP address pool.
Auto reserve IP for
the same host
Enable this if you want to reserve the IP address for the same host.
DHCP Server Lease Time
This is the period of time DHCP-assigned addresses is used. DHCP automatically assigns IP addresses to clients when
they log in. DHCP centralizes IP address management on central computers that run the DHCP server program.
DHCP leases addresses, for a period of time, which means that past addresses are “recycled” and made available
for future reassignment to other systems.
This field is only available when you select Enable in the DHCP field.
Days/Hours/Minutes DHCP server leases an address to a new client device for a period of time, called the DHCP
lease time. When the lease expires, the DHCP server might assign the IP address to a
different client device.
DNS Values
This field appears only when you select Enable in the DHCP field.
DNS The Zyxel Device supports DNS proxy by default. The Zyxel Device sends out its own LAN IP
address to the DHCP clients as the first DNS server address. DHCP clients use this first DNS
server to send domain-name queries to the Zyxel Device. The Zyxel Device sends a response
directly if it has a record of the domain-name to IP address mapping. If it does not, the Zyxel
Device queries an outside DNS server and relays the response to the DHCP client.
Select DNS Proxy to have the DHCP clients use the Zyxel Device’s own LAN IP address. The
Zyxel Device works as a DNS relay.
Select Static if you have the IP address of a DNS server. Enter the DNS server's IP address in
the field to the right.
Select From ISP if your ISP dynamically assigns DNS server information (and the Zyxel Device's
WAN IP address).
