DESCRIPTION
Interface Group
Group Name
Select the interface group name for which you want to configure LAN settings. See
for how to create a new interface group.
LAN IP Setup
IP Address
Enter the LAN IPv4 address you want to assign to your EMG 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 EMG 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 allows the EMG 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 EMG act as a DHCP server or DHCP relay agent.
Select
Disable
to stop the DHCP server on the EMG.
Select
DHCP Relay
to have the EMG forward DHCP request to the DHCP server.
DHCP Relay

Auto reserve IP
for the same
host
Select
Enable
to have the EMG record DHCP IP addresses with the MAC addresses the IP
addresses are assigned to. The EMG 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.

DNS Server 1/2
Enter the first and second DNS (Domain Name System) server IP addresses the EMG passes to the
