Configuring WAN settings
A Wide Area Network (WAN) is a widely dispersed telecommunications network. The Mobility 5181
Access Point includes one WAN port. The Mobility 5181 Access Point WAN port has its own MAC
address. In a corporate environment, the WAN port might connect to a larger corporate network.
For a small business, the WAN port might connect to a DSL or cable modem to access the Internet.
Use the WAN screen to set the WAN IP configuration and Point-to-Point Protocol over Ethernet
(PPPoE) parameters.
To configure WAN settings for the Mobility 5181 Access Point:
1. Select Network Configuration -> WAN from the Mobility 5181 Access Point menu tree.
2. Refer to the WAN IP Configuration field to enable the WAN interface, and set network address
information for the WAN connection.
NOTE
Brocade recommends that the WAN and LAN ports should not both be configured as DHCP
clients.
Enable WAN Interface Select the Enable WAN Interface check box to enable a connection
between the
Mobility 5181 Access Point and a larger network or
outside world through the WAN port.
Disable this option to effectively isolate the
Mobility 5181 Access
Point ’s WAN. No connections to a larger network or the Internet are
possible. Clients 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 check box enables DHCP for the Mobility 5181 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 Mobility 5181
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 Mobility 5181 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 Mobility 5181
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 Mobility 5181 Access Point’s WAN
connection. The ISP or a network administrator provides this address.
