We have two SonicWall TZ215's running SonicOS Enhanced 18.104.22.168-42o at two remote locations. We have a VPN setup and I have enabled the features in the VPN tunnel to allow HTTP, HTTPS, and SSH remote administration. It works properly using Google Chrome 36.0.1985.125 and Internet Explorer 11.0.9600.17126.
However, it will not allow me to login using Mozilla Firefox 31.0. It gives the me the login on Firefox, then I fill in the password, and it attempts to login but goes right back to the login screen. Mozilla Firefox is my preferred browser and I have been using Chrome to administer the SonicWalls for now but I am just curious as to why the login doesn't work.
In testing, I have removed the Self-Signed SSL Certificate from inside of the Firefox browser at the following location but it didn't make any difference on login capabilities:
Options - Advanced - View Certificates - Certificates - the remove the SonicWall certificate for that specific IP address
Then at next login, I need to click "I Understand the Risks" and then I Confirm the Security Certificate and Permanently Store it to get the login. This is the login that just keeps looping around after I enter the details and click login.
I just find it odd that it doesn't work in Firefox and wanted to see if anyone else experienced this issue. I have done some Google searches and haven't had any luck finding others with the same issues or they haven't documented it well enough to be found. For the record, I haven't tried to login locally (not over VPN) using Firefox because I don't have a local computer with Firefox but I don't believe that would be related anyways.
