The following table describes the fields in this screen.
Table 22 LAN Setup: Edit > General / IPv4
LABEL
DESCRIPTION
General
Group Name
Select the interface group name for which you want to configure LAN settings. See
for how to create a new interface group/VLAN.
Zone
Select the security zone (
LAN
,
WLAN
,
DMZ
, or
EXTRA
) in which to include the LAN interface. A
newly created local network (interface group) belongs to the LAN zone by default.
IPv4 / IPv6 Mode Select
IPv4
only
if you want the SBG to run IPv4 only.
Select
IPv4 IPv6 Dualstack
to allow the SBG to run IPv4 and IPv6 at the same time.
IPv4 Address Setting
IP Address
Enter the LAN IP address you want to assign to your SBG 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 SBG 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
Enable IGMP
Snooping
Select the check box to allow the SBG to passively learn multicast group.
IGMP Mode
Select
Standard Mode
to have the SBG 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 have the SBG block all unknown multicast packets from the WAN.
DHCP Setting
DHCP Mode
Select
DHCP Server
to have the SBG act as a DHCP server.
Select
DHCP Relay
to have the SBG act as a DHCP relay agent and forward DHCP request to the
DHCP server you specify.
Select
DHCP Disable
to stop the DHCP server on the SBG.
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.
Lease Time
This is the period of time DHCP-assigned addresses use. 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
DHCP Server
in the
DHCP Mode
field.
DNS Server 1
Specify the IP address of the first DNS server for the DHCP clients to use. Use one of the following
ways to specify the IP address.
DNS Proxy
- the clients use the IP address of the SBG LAN interface. The SBG redirects clients’ DNS
queries to a DNS server for resolving domain names.
Static
- enter a static IP address.
From Wan Interface
- select the WAN interface that receives the DNS server address from its
DHCP server.
