I am using UDP BSD sockets in C, and I need a way to receive all packets sent to my IP on a range of different port numbers. My current code can detect packets only on one port that I specify. Is this possible to do, or should I look for another way to accomplish this?

1Depending on your environment you might use raw sockets or you might firewall rules to redirect traffic destined for many ports to a single port (i.e. iptables redirect, pf divert etc) and thus get the traffic no matter what original port it was sent to. – Steffen Ullrich Dec 31 '20 at 10:28

You would need to start a listener for each port number you want to listen to

@blinded_ravager I doubt it, udp as well as tcp needs to listen to a specific port – Matt Douhan Dec 31 '20 at 06:14
