If I am using one, a VPN service, but can connect up to 8 devices, can all devices / users see the traffic of other users / devices?
Or is each VPN connection creating its own tunnel, so it basically says that only 8 tunnels can be made / created at a time?
Also, once connected to my VPN, it is possible that someone give me authentication, using my VPN too, if someone is playing with a Wifi network? I mean, in theory, if you can think of something that can be done, but I wonder if this is a problem that happens often.
What I ask is that I am living in a house with several people, sometimes I realize that they have fun upstairs, when trying to configure several access points with the same name of Wifi, I worry if they can kidnap sessions even if I am on a VPN connection (as I once noticed a message on a service that I never wrote, but when I review the session logs, the only open sessions are the ones I know). I know I had I did not write this message, therefore, I am interested in how it would be done if I was on my VPN. Although I realize that they disconnect the wifi, sometimes they make me reconnect to my VPN, etc.
For my part, I set up my VPN to disconnect from the Internet, once my VPN connection goes down, but I wonder if reconnecting immediately could cause another security issue (assuming VPNs have handshakes as a point of wifi access).
Would it be safe to say that I should invest in my own wireless router and set up a firewall? Originally, I wanted to use my Linux box with two wireless cards, set up a new wireless network with a firewall and then create a new Hotspot, protecting my devices a little more.
