The reason of creating this script is that Endpoint Security VPN installs it's own application firewall kext cpfw.kext which prevents for example PPTP connections from this computer, which is not appropriate if you need subj connection just from time to time.

# Usage: ./checkpoint.sh

# The script checks if Enpoint Security VPN is running. If it is, then it shuts it down, if it is not, it fires it up.
# Or, make an Automator action and paste the script. You will need sudo power.
#
# To prevent Endpoint Security VPN from starting automatically whenever you restart your Mac, edit this file:
# `/Library/LaunchAgents/com.checkpoint.eps.gui.plist`
# And change 
# `<key>RunAtLoad</key>`
# `<true/>`
# to 
# `<key>RunAtLoad</key>`
# `<false/>`
