5.8.4 TCP/UDP Port Filters
Port-based filtering enables you to control wireless user access to network services by selectively blocking TCP/UDP protocols
through the device. A user specifies a Protocol Name, Port Number, Port Type (TCP, UDP, or TCP/UDP), and filtering interfaces
(Only Wireless, Only Ethernet or Both) in order to block access to services such as Telnet and FTP, and traffic such as NETBIOS
and HTTP.
For example, a device 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.
Navigate to CONFIGURATION > Filters > TCP/UDP Port Filters. The TCP / UDP Port Filters screen appears.
