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
