Replicating or tapping data coming on one port to another


I have a WG VPN server and two clients in a setup

Both clients connect through a server. All three devices can ping each other. no issues

Client 1 sends a data on Port 5000 to Client 2.
I want to tap packets at server for monitoring and later forwarding to another machine for analysis.

Any idea how to do that.
Can I use prerouting table to route port 5000 to :6000?
Will Client 2 still receive data on port 5000?
