Enable WAN
Interface Select the Enable WAN Interface checkbox to enable a
connection between the
access point
and a larger
network or outside world through the WAN port.
Disable this option to effectively isolate the
access
point
’s WAN. No connections to a larger network or the
Internet are possible. MUs cannot communicate beyond
the LAN.
By default, the WAN port is static with an IP address of
10.1.1.1.
This interface is a
DHCP Client This checkbox enables DHCP for the access point WAN
connection. This is useful, if the larger corporate network
or
Internet Service Provider (ISP) uses DHCP.
DHCP is a protocol that includes mechanisms for IP
address allocation and delivery of host-specific
configuration parameters from a DHCP server to a host.
Some of these parameters are IP address, network mask,
and gateway.
If DHCP client mode is enabled, the other WAN IP
configuration parameters are grayed out.
IP Address Specify a numerical (non DNS name) IP address for the
access point’s WAN connection. This address defines the
AP's presence on a larger network or on the Internet.
Obtain a static (dedicated) IP address from the ISP or
network administrator. An IP address uses a series of four
numbers expressed in dot notation, for example,
190.188.12.1.
Subnet Mask Specify a subnet mask for the access point’s WAN
connection. This number is available from the ISP for a
DSL or cable-modem connection, or from an administrator
if the access point connects to a larger network.
A subnet mask uses a series of four numbers expressed in
dot notation (similar to an IP address). For example,
255.255.255.0 is a valid subnet mask.
Default Gateway Specify the gateway address for the access point’s WAN
connection. The ISP or a network administrator provides
this address.
Primary DNS
Server Specify the address of a primary Domain Name System
(DNS) server. The ISP or a network administrator provides
this address.
A DNS server translates a domain name (for example,
www.extremenetworks.com) into an IP address that
networks can use.
Secondary DNS
Server Specify the address of a secondary DNS server if one is
used. A secondary address is recommended if the primary
DNS server goes down.
