Function description: This switch allows you to configure each port you want to limit or allow the TCP/UDP protocol type to get through, such as HTTP, FTP or TELNET and so on.
Parameter description: Function Enable: Enable/ Disable this TCP/UDP Filter.
Port Filtering Rule: Deny means that the selected TCP/UDP protocol types will be dropped to the specified port and allow other protocol packets to be forwarded. Allow means that only the selected TCP/UDP protocol types will be forwarded to the specified port and other protocols packet will be dropped.
