Change Windows Firewall From Command Line or Batch File

I have a set of scripts I run when I prep a computer for deployment. Â At specific points applications require that the windows firewall be turned off in order to install correctly. Â This is namely ACT! and imagine time. Â They use a bunch of odd ports during install, so their documentation tells you to just turn off the firewall. Well here is what I found with a little research. Â From run or in a batch file there is a simple netsh command to disable the firewall and one to again enable it.

For imagine time my install script looks like this

netsh firewall set opmode disable
g:\Imagine_time\IT_SETUP.exe /q /p
netsh firewall set opmode enable

Â
EffectivelyÂ this will turn off the firewall, install the software silently from a share, and then enable the firewall again after install. I foundÂ somethingÂ interesting with this in regards to kaseya too. Â Sometimes VNC can’t get through the firewall because it hasÂ defaultedÂ or something went wrong. Â It turns out that if you run this as “system” you can actually disable the firewall remotely in many cases. Â This has been a veryÂ helpfulÂ script for when a computer shows ‘connectable’ but it just times out when attempting connection.

Script Name: Win Firewall Off

Script Description: Turns off windows firewall

IF TrueÂ

THEN

Â Â Execute Shell Command

Â Â Â Parameter 1 : netsh firewall set opmode disable

Â Â Â Parameter 2 : 1

Â Â Â Â Â OS Type : 0

ELSE

Additionally, Â if you change enable to disable in the above script, you can enable the firewall remotely through kaseya as well.
