Logout SBG6782-AC Advanced - Port Filtering Home > Advanced > Port Filtering --> The SBG6782-AC can block ports from being accessed by services. Your SBG6782-AC's Firewall and Port Filtering Ports are virtual pathways numbered between 0 and 65535 that the SBG6782-AC and other devices use to sort incoming and outgoing network traffic. Your network's security can be improved by blocking and filtering communications going through the SBG6782-AC's ports. In general, you should not manually filter ports unless you have a specific reason to do so. For most people, the SBG6782-AC's firewall (when active) provides a good level of security by blocking ports except those used by common services. (The firewall, based on its settings, blocks many or all ports from access by services. The firewall is like a pre-set port filtering / blocking service.) See the Firewall - Protection page for firewall settings. Request 80 Filtered Port or Filtered Port Range Block a Single Port from Use by Services You may want to filter a single port to block services that would use that port. To do this, you could create a port filter with an identical Start Port and End Port, like 80, and selecting UDP, TCP, or Both for the affected protocol. You could then enable the filter by checking the Enabled box and pressing Apply. Later, any service attempting to use that filtered port would be blocked. Block a Range of Ports from Use by Services You may want to filter a range of ports to block services that would use that range of ports. For example, you could create a Start Port filter at the beginning of the range (80) and an End Port filter at the end of the range (210). You could then enable the filter by checking the Enabled box and pressing Apply. Later, when any service attempts to communicate over a port between 79 and 211, the service will be blocked. Port Filtering --> Start Port The starting port number of the range of ports that will blocked --> --> End Port The ending port number of the range of ports that will blocked --> --> Protocol Each communications protocol uses one of two fundamental protocols to transmit its data on the Internet: User Datagram Protocol (UDP) or Transmission Control Protocol (TCP). Typically, only one or the other is used for any given communications protocol, but sometimes the other is used for special applications --> --> Enabled Enables the range of ports to be blocked. If this is not enabled, the ports are not blocked --> TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both TCP UDP Both ©2015 ARRIS Group, Inc.
