Tcp/Udp Port Filters - Proxim ORiNOCO AP-800 Installation And Management Manual

3.8.4 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.
To configure TCP/UDP Port Filters, do the following:
1. Navigate to CONFIGURATION > Filters > TCP/UDP Port Filters. The TCP / UDP Port Filters screen appears.
2. Filter Control: Specifies the Filter Control feature on the device. By default, it is disabled. To configure, select Enable
or Disable from the drop down menu.
3. Click OK, to save the configured parameters
