It seems like we are spinning our wheels trying to chase down individual VPNs that our students are using to circumvent our security measures. We give special priority to certain very evasive VPNs like Ultrasurf, Psiphon, Hotspot Shield, Freegate, etc because they employ very complicated protocols to bypass firewalls. VPN Blocking Best Practice We are currently working through blocking VPN's on our FortiGate 600D.

How to crack fortinet firewall vpn update#
We have our tools that monitor when these apps are updated and we update our signatures accordingly. STEP BEnter the address of the website being filtered by the Fortinet software in the text box on the top of the Freeze the Firewall screen. The remaining VPNs that are not covered by the signatures above are covered by the other signatures in our Proxy category. For iOS VPNs, because of strict restrictions by Apple that VPNs need to use PPTP, L2TP or IPSec (we name the signature ISAKMP), blocking those 3 signatures would block most of the VPNs on iOS. This signature works for most of Android and Windows VPNs. For those that do not use the OpenVPN protocol, many share the same servers or API calls. To my dismay, however, Fortinet blocked my connection to my VPN. I decided to try bypassing it with OpenVPN, which has been successful at other schools I have attended. It blocks multiple applications and sites that I use regularly, like Spotify, YouTube, and Reddit. As to how we try to cover all the VPNs, from our research, 80-90% of the common VPNs in the market use some forms of the OpenVPN protocol that our "OpenVPN" signature would block. At my school, there is a very annoying Fortinet filter/firewall. That should block most if not all the VPNs you can find. Hello zwilson50, To block the VPNs, please set the category "Proxy" and the signatures "PPTP", "L2TP" and "ISAKMP" to Block.
