I have recently began using NetWorx. I am wondering if there is an option in the Linux version to ignore local LAN traffic or block a specific IP, like there is in Windows version. I have a NAS and it's throwing off my upload and downloads.
No, I am afraid this functionality is not available in the Linux or macOS versions. Filtering traffic by IP address requires a network driver to be installed, or a reliance on a third-party package like libpcap, which comes with extra implications like requiring root privileges.
We may be able to implement it in the future, but at the moment individual IP addresses cannot be filtered out.
