Packet Sniffer

1
Hi,
I have a client and a server and I need to make a server-side packet sniffer that check what's incoming to the server..
I thought I could make a packet sniffer that recieve UDP data from the client and redirect, after the check, to the server..but the server runs on a specific port and I cannot change it.
That's my first time working on a packet sniffer and I have to make a class for that 'couse it's gonna be a part of a program.
Can someone give me some ideas about sniffing UDP traffic on a port where a server is running? ty
