@Danila T. Im so sorry, I did check by wifi… not use ethernet. When I use ethernet, it still stuck on Mac OS 12.3.

@Danila T. Thanks for your response. It starts to work well on macOS 12.3 even if I removed exclusion settings. It has fixed from this os version 12.3. Thanks a lot!

Here are the screenshots which show configured exclusion, IP address and MAC address. (they are masked like you mentioned)

Thanks for the response. I did create an exclusion for the Caldigit ts3 plus, but it keeps blocking the network. Could you check my step for the exclusion is correct? Get IP address (*1) and mac address (*2) for the ethernet on caldigit ts3 plus. set exclusion (Protection > Network Attack Blocker > Preference > Edit the list of trusted computers) Input IP address (*1) and enter Input Mac address (*2) and enter The list displays like this: [IP Address]/32 ::[Mac address]/128

Im not sure this is the same issue as below. Link I can not use internet by using ethernet on usb-hub (Caldigit ts3 plus) But if I unselect the Enable Network Attack Blocker on kaspersky settings, the internet starts working well. Note: wifi is working well always. Spec: M1 max macbook pro 14inch / Monterey 12.2.1 / Kaspersky 21.1.0.150c /Caldigit ts3 plus
