5.3 Enabling Wireless LANs (WLANs)
A Wireless Local Area Network (WLAN) is a data-communications system that flexibly extends the
functionalities of a wired LAN. A WLAN does not require lining up devices for line-of-sight
transmission, and are thus, desirable. Within the WLAN, roaming users can be handed off from one
AP-5131 to another like a cellular phone system. WLANs can therefore be configured around the
needs of specific groups of users, even when they are not in physical proximity.
Use the AP-5131’s Wireless Configuration screen to create new WLANs, edit the properties of
existing WLANs or delete a WLAN to create space for a new WLAN. Sixteen WLANs are available
on the AP-5131 (regardless of single or dual-radio model).
Transport Use the Transport pull-down menu to specify the transport
protocol used in this service. The choices are ALL, TCP, UDP, ICMP,
AH, ESP, and GRE.
Start Port and End Port Enter the port or ports used by the port forwarding service. To
specify a single port, enter the port number in the Start Port area.
To specify a range of ports, use both the Start Port and End Port
options to enter the port numbers. For example, enter 110 in the
Start Port field and 115 in the End Port field.
IP Address Enter the
numerical (non DNS name) IP address to which the
specified service is forwarded. This address must be within the
specified NAT range for the associated WAN IP address.
Translation Port Specify the port number used to translate data for the service being
forwarded.

unspecified ports to
Use the Forward all unspecified ports to checkbox to enable
port forwarding for incoming packets with unspecified ports. In the
adjacent area, enter a target forwarding IP address for incoming
packets. This number must be within the specified NAT range for
the associated WAN IP address.
