PC(Cable) x Android(wireless) issue with MAC Filter

Description

I was using the app just fine, but after setting up a MAC filter on my modem, neither the PC or Smartphone can see each other. Disabling the MAC filter make then work normally, só I am 100% sure the issue is the MAC filter.

Devices

Computer to Smartphone.

Phone:
Android 14
Xiaomi POCO X5 5G
AudioRelay 0.26.1

Laptop:
BRX, Windows 11
AudioRelay 0.27.5

Edit; both can access the internet it the MAC filter enabled, the issue is not Random Mac or misconfiguration.
