Do we need to have the Windows firewall ON?    When we have firewalls set on our Sonicwall VPN devices?   Or is it best practice on a network to have them both turned on?  

Windows firewall is causing some hiccups when trying to update AVG and the firewall is on, and I am trying to use the Admin console with AVG to PREVENT going and touching each PC.

Thanking you in advance for any advise

    Sorry....   I am referring to the Windows firewall on the individual user PC

    So the short answer is no. But that doesn't say it all. Windows firewall prevents unneeded ports from being needlessly open. That being said, good network security planning, proper desktop permissions for end users, a windows update policy, and a reliable antivirus / anti-malware suite will provide you the protection you need.

    You can just leave it enabled, and open the proper ports and allow required applications.

    Typically turn off windows firewall with the Sonicwall. As long as your Sonicwall definitions are up to date, and you have not opened ports directly to any pc, you should be fine. I have been doing it that way for years without issue.

    Keeping your firewall on each pc is recommended good practice because it helps protect each individual pc if something does get through the main firewall onto a pc within the firewalled area.
