LABEL DESCRIPTION
Interface Group
Group Name Select the interface group name for which you want to configure LAN settings. See Chapter 15
on page 194 for how to create a new interface group.
LAN IP Setup
IP Address Enter the LAN IPv4 IP address you want to assign to your Zyxel Device in dotted decimal
notation, for example, 192.168.1.1 (factory default).
Subnet Mask Type 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.
IGMP Snooping
Active Select Enable to allow the Zyxel Device to passively learn multicast group.
IGMP Mode Select Standard Mode to forward multicast packets to a port that joins the multicast group and
broadcast unknown multicast packets from the WAN to all LAN ports.
Select Blocking Mode to block all unknown multicast packets from the WAN.
DHCP Server State
DHCP Select Enable to have the Zyxel Device act as a DHCP server or DHCP relay agent.
Select Disable to stop the DHCP server on the Zyxel Device.
Select DHCP Relay to have the Zyxel Device forward DHCP request to the DHCP server.
DHCP Relay
Server Address This field is only available when you select DHCP Relay in the DHCP field.
IP Address Enter the IPv4 IP address of the actual remote DHCP server in this field.
IP Addressing
Values This field is only available 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

Auto reserve
IP for the
same host
Click this switch to have the Zyxel Device record DHCP IP addresses with the MAC addresses the
IP addresses are assigned to. When the switch goes to the right
, the function is enabled.
Otherwise, it is not.
The Zyxel Device assigns the same IP address to the same MAC address when the host requests
an IP address again through DHCP.
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
Enter the lease time of the DHCP server.
DNS Values This field is only available when you select Enable in the DHCP field.
DNS Select the type of service that you are registered for from your DNS service provider ( From ISP ).
Select DNS Proxy if you have the DNS proxy service. The Zyxel Device redirects clients’ DNS
queries to a DNS server for resolving domain names.
Select Static if you have the static DNS service.
