My VPN won't connect when on school Wifi

VPN
1

It works everywhere else and selcting a different country won’t fix it either. What should I do? Also, I’m using a Mac and I also don’t understand any of the more advanced talk like TCS and like port 22 or whatever it’s called

You should congratulate the network admins at your school for being good at their jobs.

3

Try the Obfuscated servers

4

on Firewalls you can block services like VPN, ssh, RDP. With that no matter what port you change it to it will be blocked. kinda impressed that they did that at a school. Good job!!!

Congratulate the network admin lol. Anyways this happens because of deep packet inspection. There is one thing you can try -

  1. Open NordVPN

  2. Settings > Connections > Protocol and use OpenVPN (TCP) or (UDP) (try both).

  3. Either of them must help you connect either via normal connection or Obsfuscated servers.

6

If you’re on a Mac try following Nords instructions for setting up IKEv2 as that might work. Some education providers are particularly tough with firewalls but they have to be for safeguarding purposes.

7

But technically what’s happening? Do school administrators have a list of VPN services that they update and block?

8

Where would I find that

9

lol I know. Also what are ports? I just used an obfuscated server and it worked

10

I’m not the firewall guy but we’re a Cisco shop and recently blocked all VPN access. I was told it was basically as simple as clicking a button. Cisco essentially already had the function programmed into their firewall rules.

Are you on IOS? Windows?

12

If we post it, then it’s no longer hidden.

Seriously though, it should be 443

Np, update if it worked

Oh, you asked what are ports, and not “what ports.”

Basically, your computer needs to communicate with a server on a specific IP address. Think of an IP address as a phone number. This phone number can only be reached at a specific time. At no other time would the server answer the call. That would kind of like be what a network port is.

Port 443 is SSL/TLS. If someone blocked that port, most of the Internet would break. Port 22 is SSH.

To make things even more interesting, there are two types of packets, TCP and UDP. This is a much deeper topic, that it’s best you take a class on it.
