Question Intercepting and redirecting unity game network traffic to a specified network route.

I am currently working on a network project, and I am trying to intercept Unity multiplayer game network traffic and redirect it to a specified network route using Photon or Mirror networking engine; however, I could not find a script file or code that is responsible for the network routing and packet forwarding to modify the algorithm or to override existing methods.

Would anyone please help me in this situation to guide me in the right direction? Knowing that I am new to the Unity platform.
