Are Doom source ports legal?
As of today, the majority of Doom source ports are open source. The GNU GPL requires that authors who use GPL code in their software must release the modified source code as well.
Are source ports random?
The source port is most often randomly picked by the computer. The source port can be used by routers and firewalls in the network to distinguish between different communication flows or sessions since each session will have a different random source port associated with it.
How do source ports work?
Source ports are randomly generated from the unregistered port range. The source/destination port works similar to your IP. The port you send from, is the port the service will reply too. For instance; a website is simply a server listening for connections on port 80 (or 443).
What is source port in networking?
The source port is a next-available number assigned by TCP/IP to the user’s machine. This assigned client number is how the network address translation (NAT), which typically resides in the router, determines which user to send back the responses to.

Is source port the same as destination port?

Why is source port needed?
What is port no 6666?
Side note: UDP port 6666 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 6666 makes possible the transmission of a datagram message from one computer to an application running in another computer.
