    Hi @joudeh1996,
    Welcome to Zyxel community. :) You can block VPN service by App patrol.
    1) Go to CONFIGURATION >  UTM profile > App patrol, and select "Bypass_Proxies_and_Tunnels service" to create app profile.

    2) Apply app profile to security policy at CONFIGURATION  > Security Policy > LAN_Outgoing.

    So I decided to activate my Trial on Zywall 110 (updated the Signature) to block this Psiphon and even with only ports 80,443,53 to block this it was allowed. Now this is not surprising to me you can bypass anything to look like normal traffic.

    So what are your options...well you could block the IP of the servers which will take time to do and thats if they don't change over time.

    Hi @joudeh1996,
    We would like to conduct a lab test.
    Did you test on Mobile version(IOS/Android) or Windows Desktop version?
