If I connect a second computer to my router using an ethernet cable, how much traffic can that new computer potentially see? Currently I have two computers connected to my router via ethernet cables; one is my personal computer, the other is one issued to me by my work. I understand that the work computer would at least be able to see some basic packet information but I'm wondering if it could see more specific details, or get access to any folders I'm sharing on the network. While I doubt that they're trying to see any network activity that isn't going through their VPN, I just think I'd be better off safe than sorry. Additionally, are there any steps I can take to limit what this second connection can see and do?
Thank you!
