Hi,

I enabled app control and I blocked all proxy access.

I blocked VPN in app control

SOnicwall NSA2650 app control is not working.

Browser with VPN incorporated such as epic privacy browser bypass the firewall and all rules.

I have already tried to enable dpi ssl but with no result

    Make sure you blocked the Hacking/Proxy Avoidance Systems category in CFS policy.

    Hi @reynold85

    what is the type of proxy web site or technologies? could you give more information about proxy software and screen shots?

  • Bako_SalamBako_Salam Newbie ✭

    @MitatOnge sir the problem is when you have some rules on the firewall , users can download any VPN software on store and use it to bypass which is something that sonicwall clamis to be solved but unfortunetly dose not work at all . no one knows or have a solustion. let me give you a simple example, FB App blocked , user 192.168.0.10 will download some VPN like hotspotshield or VPN super or any others VPN software and bypass this rule easly . if anyone has an idea please dont histate to share . BTW VPN category is blocked in APP rule.

    Hi @Bako_Salam


    please try below kb for hotspot shield. you should enable DPI-SSL for all clients and create app firewall rules.
