If I am using one a VPN Service, but it allows up to lets say 8 devices to connect, are all the devices/users able to view traffic from other users/devices?
Or is each VPN connection creating its own tunnel, thus its basically saying that only 8 Tunnels can be made/created at once? Also once connected to my VPN is it possible for someone to de-authenticate me, using my VPN also, if someone is messing around with a Wifi-Network? I mean in theory if you can think of something it can be done, but I am wondering if this is an issue that happens often?
Why I am asking is I am living in a house with multiple people, I notice they are having some fun upstairs sometimes, by trying to setup multiple hotspots with the same Wifi name, I am concerned if its possible that they can do session-hijacking even if I am on a VPN connection (as one time I noticed a message on a service I use that I never wrote, but when checking logs of sessions, the only sessions open are the ones I am aware of.) I know I had not written this message, thus I am interested in how it would be done if i was on my VPN. Although I notice they disconnect the wifi often sometimes having me reconnect to my VPN etc. On my end I have setup my VPN to disconnect me from the internet, once my VPN connection drops, but I am wondering if reconnecting right away might cause another security issue (assuming vpn's have handshakes also just like a wifi hotspot)? Would it be safe to say I should invest in my own wireless router and setup a firewall? I wanted to originally use my Linux box with two wireless cards, setup a new wireless network with a firewall and then create a new Hotspot, thus protecting my devices a little bit more.
