Kind of a big deal

Re: Browser Extension based VPN

From my point of view, those should also be covered by "Proxy Avoidance" using Layer 7 rules.

Re: Browser Extension based VPN

Upon checking, there is no "Proxy Avoidance" on the layer 7 firewall rules.

We are using MX400 version MX 14.53

 

Only got this

Also, we have filtered it below:

But still VPN from the browser is able to bypass the firewall and able to access the internet without restriction

@ecejhe : the VPNs are under the category of "Proxy Avoidance and Anonymizers" which you did i saw. Create outbound deny rules for ports 500, 1701, 4500, and 1723
