I have set up a local network and I would like to know what devices are connecting to what web servers, identify MAC address, timestamp and if someone is using a VPN, can I still get that same info? Additionally, but no as important, is there a way to see if the info sent is of a specific file type? .docx or .pdf?
Thank you very much, I'm new at this and would like to learn more but I'm having trouble finding what to know.
