Worklet: Install Forticlient VPN and provision gateway

Hi Guys, We use Fortigate Firewall/VPN Concentrators and needed an easy way to push out the newest client with all the gateway settings pre-applied. Shoutouts to @awhitman for helping point us in the right direction with a couple free professional hours.

So basically what we do is run the installer, and then in order to actually modify all the settings we want, we need to throw some regkeys in the HKLM-Software hive. This will allow us to push the app to the end user and its prepopulated with the right URL/path/etc

It’s worth noting, theres 2 versions of the forticlient VPN software, online and full. Online is readily available but if you want the full installer, you need to logon to forticare and download it behind a membership wall.

Things to change:
$pathtourl is your publically accessible vpn concentrator
$gateway is what the end user will see for a friendly name.

Start-Process -Wait -FilePath "FortiClientVPNSetup_6.4.1.1519_x64.exe" -ArgumentList "/S /v /qn /norestart" -passthru

$scriptblock = {
$pathtourl = "Your VPN PATH HERE"
$gateway = "Your desired description name"

$path1 = "HKLM:\\SOFTWARE\Fortinet\FortiClient"
$path2 = "HKLM:\\SOFTWARE\Fortinet\FortiClient\Sslvpn"
$path3 = "HKLM:\\SOFTWARE\Fortinet\FortiClient\Sslvpn\Tunnels"
$RegKeyExists = "HKLM:\\SOFTWARE\Fortinet\FortiClient\Sslvpn\Tunnels\$gateway"
New-Item -Path $path1 -Name "Sslvpn"
New-Item -Path $path2 -Name "Tunnels"
New-Item -Path $path3 -Name "$gateway"
New-ItemProperty -Path $RegKeyExists -Name 'promptcertificate' -Value '0' -PropertyType DWORD -Force
New-ItemProperty -Path $RegKeyExists -Name 'promptusername' -Value '1' -PropertyType DWORD -Force

New-ItemProperty -Path $RegKeyExists -Name 'ServerCert' -Value '1' -Force
$exitCode = & "$env:SystemRoot\sysnative\WindowsPowerShell\v1.0\powershell.exe" -ExecutionPolicy Bypass -WindowStyle Hidden -NoProfile -NonInteractive -Command $scriptblock
Exit $exitCode
