Getting Started
Set a minimum set of parameters for using the WAN interface.
a 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 connection. No connections to a larger network or the Internet will be
possible. MUs cannot communicate beyond the configured subnets.
b Select the This Interface is a DHCP Client checkbox to enable DHCP for the access point's 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.
NOTE
Extreme Networks recommends that the WAN and LAN ports should not be configured as DHCP clients
at the same time.
c Specify an IP address for the access point's WAN connection. An IP address uses a series of four
numbers expressed in dot notation, for example, 190.188.12.1 (no DNS names supported).
d 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. For
example, 255.255.255.0 is a valid subnet mask.
e Define a Default Gateway address for the access point's WAN connection. The ISP or a network
administrator provides this address.
f Specify the address of a Primary DNS Server. The ISP or a network administrator provides this
address.
