The short answer

  • 1.App-ID technology can identify many VPN protocols, and administrators choose whether to block them.
  • 2.On networks you don't control, blocked VPNs are a policy decision, not a fault.
  • 3.Request access, use an allowed network or use your mobile data when your own privacy is the concern.

What detection really is

Next-generation firewalls identify applications by their traffic patterns instead of just port numbers. An administrator can then permit, restrict or log categories like VPN or proxy.

Sensible options

  • →Office or school network: follow the acceptable-use policy; ask the network team for an exception if you have a need.
  • →Hotel or cafe network: try a different protocol or port from your VPN's settings; these networks block less strictly.
  • →Your own network: you control the firewall, so nothing needs bypassing.
  • →Anywhere: your phone's hotspot is a simple alternative to a restrictive network.
