Filtering
4-94 Avaya Wireless AP-4/ 5/6 User’s Guide
The AP can filter these protocols in the wireless-to-Ethernet direction, the
Ethernet-to-wireless direction, or in both directions. Click Edit and use the
Status field to Enable or Disable the filter.
TCP/UDP Port
Port-based filtering enables you to control wireless user access to
network services by selectively blocking TCP/UDP protocols through the
AP. A user specifies a Protocol Name, Port Number, Port Type (TCP,
UDP, or TCP/UDP), and filtering interfaces (Wireless only, Ethernet only,
all interfaces, or no interfaces) in order to block access to services, such
as Telnet and FTP, and traffic, such as NETBIOS and HTTP.
For example, an AP with the following configuration would discard frames
received on its Ethernet interface with a UDP destination port number of
137, effectively blocking NETBIOS Name Service packets.
