Nov 02, 2017 · Port numbers 0 to 1024 are reserved for privileged services and designated as well-known ports. This list of port numbers are specified in RFC 1700. In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. IANA is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. This includes the registration of commonly used port numbers for well-known Internet services. The port numbers are divided into three ranges: the well-known ports, the registered ports, and the dynamic or private ports. Ports allow a single host with a single IP address to run network services. Each port number identifies a distinct service, and each host can have 65535 ports per IP address.

Troubleshooting Port Forwarding and NAT Rules - Cisco Meraki If the traffic in question reaches the Internet interface of the MX, but is not forwarded on, ensure that the destination port and protocol of the traffic matches the configured port forwarding rule. If attempting to access a web server using HTTPS (TCP:443) and a forwarding rule has only been configured for HTTP (TCP:80), then the HTTPS
