3-26 Port Filtering

Port filtering enables you to control all data that can be transmitted over routers. When the port used at the
source end is within the defined scope, it will be filtered without transmission.
Enable Port Filtering: Select to enable this function.
Port Range: Set the range of ports to be filtered. If, for example, the port to be filtered is 80 and the
selected protocol is both or TCP, all computers will be unable to use HTTP services (port 80) and will be
unable to browse normal webpages.
TCP/UDP: Choose to filter TCP, UDP, or both.
