i have liked your presentation please keep on bring such. however, this vpn "Proton" still by bypasses the firewall. ill be great fully if you can share how to block it
No I already tested all vpn, if you disable UDP protocol then, you can block almost all vpn, I already tested. And successfully blocked.
I want to learn more on this content.... with course i need to take plz suggest me
Can i use the same method by blocking UDP in open source firewall ? For example OPNSENSE
Yes, its possible, but you have to block in application too. some VPN can bypass like thunder vpn. so once you implement you have to test the connection.

@@OmarAli-vl4zy yes dear, its free, you can 95% features are free. and it's stable to use. i recommend you. if you have a old pc with 2 lan interface you can use.
@@gadgetstipstricks5422 Thank you so much for the help!
i have tried the same but still users are able to connect to super vpn , i believe app is using udp protocol
yes, ofcourse super VPN and most the VPN use UDP protocol for best performance. so you have to disable or remove UDP protocol.
@@gadgetstipstricks5422 Blocking the UDP will affect other applications as well
@@mohsinalibhatti7072 Of-course it will affect other application, If you are using OPENVPN to connect your company branch etc. or any other UDP protocol, it will not work if you close all the UDP port, so better option is add only particular UDP port depends upon your requirements.
i have very strict rules in my environment but beside this user can access to websites using these paid vpns
