Hi everyone,

I'm currently facing some frustrating restrictions with the public Wi-Fi at my school. It's an open Wi-Fi network without a password, but the school has implemented a firewall (Fortinet) that blocks access to certain websites and services, including VPNs like Mullvad and ProtonVPN. This makes it difficult for me to maintain my privacy online, especially since I don't want the school to monitor me excessively.

After uninstalling Mullvad, I tried to download it again, but I found that even a search engine (Startpage) is blocked, which is incredibly frustrating! Here’s what happened:

  • The Wi-Fi stopped working when I had the VPN enabled.
  • I disabled the VPN, but still couldn't connect.
  • I forgot the Wi-Fi network and reset the driver, but still no luck.
  • I uninstalled the Mullvad, and then the Wi-Fi worked again.
  • I tried to access Startpage to search for an up-to-date package for Mullvad, but it was blocked.
  • I used my phone to get the software file and sent it over, but couldn't connect.
  • I searched for different VPNs using DuckDuckGo, but the whole site was blocked.
  • I tried searching for Mullvad, but that was blocked too.
  • I attempted to use Tor with various bridges, but couldn't connect for some unknown reason.
  • I finally settled for Onionfruit Connect, but it doesn't have a kill switch, which makes me uneasy.

Ironically, websites that could be considered harmful, like adult content, gambling sites and online gaming sites, are still accessible, while privacy-tools are blocked.

I'm looking for advice on how to bypass these firewall restrictions while ensuring my online safety and privacy. Any suggestions or alternative methods would be greatly appreciated! (If any advice is something about Linux, it could be a Problem, since my school enforces Windows 11 only PC's which is really really igngamblingThanks in advance for your help

edit: did some formatting

edit2: It is my device, which I own and bought with my own money. I also have gotten in trouble for connecting to tor and searching for tor, but I stated that I only used it to protect my privacy. Honestly I will do everything to protect my privacy so I don't care if I will get in trouble.

edit 3: Thanks for the suggestions, if I haven't responded yet, that's because I don't know what will happen.

Hi! Back in high school, me and a few close friends formed a small hacking group aimed at hacking the school WiFi. We succeeded, and reported the vulnerabilities we found along the way to the school. Our school had a policy where students who managed to hack something would be let off the hook if they reported exactly how they did it. I managed to land a job for the school district as a result of our fiasco. I don't recommend anyone do that, but I managed to get lucky.

Anyways, once we had access to the WiFi we wanted to get around the network wide filter. Proton VPN worked for a while, but quickly got blocked. Dual booting into Tails on school computers didn't work until the 6.0 update. To my knowledge, it still works.

However, for our phones, the thing that worked was changing the DNS. We found out the network wide filter the school boasted so highly about was only a DNS filter that resolved hostnames to a "blocked" page. Find a good PRNS and change your device's DNS to match. If you want a search engine, try to find an unblocked SearXNG instance.

Good luck!

P.S. Don't forget: Tor is portable on Windows devices :)

This is the best answer. You didn't go charging through their system with complete disregard. You made the IT staff like you first, then broke through their system. That's social engineering at it finest here people, and is the first skill any great hacker needs to learn. Please do good with this skill.
