What do you do if 100 percent of the games you play are blocked at school

If your browser is Firefox then you can easily just go into options on the browser and pop in some proxy/VPN creds and it bypasses everything.
But if your school computers do not have access to Firefox, just install it on a flash drive and bring it to school, pop in the creds and your ready to go.

And even though it might say inside your school handbook that you may not tamper with the schools network or its computers at any giving time, you do have the right to privacy, and since the schools network has not blocked the proxy/VPN addresses, then its their fault. You did not, in anyway, "Hack" the computer,firewall,or the schools network, you basically just added a layer of protection to your work, and on the monitoring side, it would just look like you were just transmitting a lot of encrypted data to one address.

I have done this with my iPhone and I was called in to the office because my activity though my account with the network was encrypted and they wanted to see what I was doing. Since I knew my full rights, they have NO right to see what im doing, if their monitoring services are not showing them what they want, that's their problema. I told them flat out that what you see there is what you get, Im not tampering with anything. They haven't called me into the office since, and I still continue with what I do on my VPN.
