Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server. There are also ports for Cluster and client status (Port 1110 TCP for the former, and 1110 UDP for the latter) as well as a port for the NFS lock manager (Port 4045 TCP and UDP).

Common ports, such as TCP port 80 (HTTP), may be locked down — but other ports may get overlooked and be vulnerable to hackers. In your security tests, be sure to check these commonly hacked TCP and UDP ports: TCP port 21 — FTP (File Transfer Protocol) TCP port 22 — SSH (Secure Shell)

This address (both IP and port) will look something like 192.168.0.168:25565 . Users connecting from the Internet (i.e., outside of your local network) must connect using your external IP address. You must port forward for someone outside your network to connect to the server.

About TCP/UDP Ports Port 0 to 1023: These TCP/UDP port numbers are known well-known ports. These ports are assigned to specific server sevice by the Internet Assigned Numbers Authority (IANA). For example, port 80 is used by web servers.

“Well-Known" ports are port numbers that have been reserved for common applications, typically server applications. The port numbers assigned to these server applications have to be known by the client's Transport layer, so they can add the correct destination port number to messages.

Several different types of physical ports available on computer network hardware include: Ethernet ports: Square-shaped connection points for Ethernet cables. USB ports: Rectangular-shaped connection points for USB cables. Serial ports: Round-shaped connection points for serial cables.
