![]() This has saved a few companies I take care off from Ransomware attacks. The only good news is if someone from https:/ Opens a new window / is not in the bypass list, they get checked or HTTPS warns of the man-in-the-middle, either way, it forces an IT person to look at the issue and prevent the attack.Granted, this is not idea, but HSTS and other rules prevent the SonicWALL from being in the middle. What I have learned I have to do is setup bypasses for know sites. I've also had to do this for various banking sites as well with HSTS setup. That's because Google is setup with HSTS and figures out SonicWALL is the middle. This is simple, just add *. and *. to the bypass list. Now, here's the catch, for Google, you have to tell the SonicWALL NOT to get in the middle. Also, from the Sonicwall, you can download the SonicWALL's certs and put them on the PCs manually or with a Group Policy. With SonicWALL DPI-SSL, SonicWALL is in the middle and the SonicWALL can decrypt it. Since it's a HTTPS site, most firewalls can't see what's in there. The goal with DPI-SSL is someone sends a bad link via email to someone in the company. DPI-SSL on SonicWALL acts as a true "man-in-the-middle" attack. For example, you can't use it on Google based cloud due to HSTS. I have used the DPI-SSL since 6.2.x.x and it takes some getting use to. I have not had this issue myself, but have come across the post on here: The current work around is to disable CFS under DPI-SSL and Enable HTTPS Content Filtering under the Advance tab of your CFS Profile Objects.Ä£.) Cannot login to the admin page of the SonicWALL. There is a current known issue in 6.5.4.4 with CFS built into the DPI-SSL engine. If you have that problem, try the solution below. If you login to the firewall as an admin and then try and access the page, it will load right away. Refreshing the page sometimes resolves the issue. You can add it back in by following the steps in their KB:Ä¢.) Web sites slow to load or don't load. SonicWALL removed a GoDaddy cert from 6.5.4.4. ![]() Opens a new window If you get the connection reset error, then follow the steps below. I've seen some posts out there and had some of my own posts.Ä¡.) Web sites not loading that use GoDaddy Certificate.
