Nope. The server receives UDP packet from WiFi and sends reply over Ethernet, which simply gets lost in your router. From the Linux side there’s no error, it sent the packet somewhere, and what happens next is your router’s problem.

That’s the think about UDP packets… receipt isn’t acknowledged as part of the protocol. It’s send and forget. I’m not sure a UDP packet sent to my server would get lost but I’m not 100% certain there couldn’t be situations where the packet is received by the server on both interfaces, essentially duplicated. It’s been almost 30 years since I wrote programs that utilized UDP for communicating. I’m definitely a little rusty. 😄
