It should be possible to see that you have 10 machines on your LAN but access to those PCs in better than 99.99% of the time is limited to "you have 10 machines connected to the router."
Now the more paranoid would never run Windows so I'll reveal that when I travel I sometimes boot up TAILS (the OS) from https://tails.boum.org/ because I can't be sure what is being done on those networks.
If an ISP did misbehave it would be in the news and the end of that company.
Hi, first of all forgive me for my ignorance in this regard... im using the isp provided router and i know they have root aces to it o perform updates, at least its what they tell us..My question is, what can they see when they remote acess the device, can they see the machines on the network, can they somehow acess them undetected even if using a third party firewall on those machines? Everytime we connect to the device to acess the internet we are sending receiving local traffic can they somehow use this to remote acess our machines undetected?
And lastly, im not sure if they allow the full replacement of the router, but if not what would be the best way to prevent them to have acess to our local network?
I know i sound paranoid but i-m always concerned to what the isp employees, those with malicious intentions in their hearts might be doing in the background...
