Barracuda Network Access Client

Fully Preconfigured Custom Installation

  • Last updated on

The silent.cmd setup is a comprehensive installation method, allowing you to fully preconfigure all Network Access Client settings remotely on multiple installation systems. The silent.cmd setup is only available for the Barracuda Network Access Client. It requires administrator rights on the target system. Only experienced system administrators should perform this method. 

Installation Using a silent.cmd File

Prepare the install file and execute an unattended customer setup.

Step 1. Prepare the silent.cmd File:

Save the following to silent.cmd file:

@echo off 
REM installs VPN-only version of NAC (VPN components + Virtual Adapter)
REM use “PROGTYPE=ENTEGRA” instead to also install NAC/Firewall components
start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN REBOOT=Suppress"

REM uncomment to import custom application settings (e.g. VPN profiles)
REM reg import mysettings.reg

REM uncomment to add Credential Provider
REM start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN ADDLOCAL=CommonCore,DrvCudaVPN,x64VPN,x64CredProv REBOOT=Suppress"

The registry file (mysettings.reg) is used for optional import of custom application settings (e.g. VPN profiles) as they can be found in HKEY_USERS\.DEFAULT\Software\Phion\.

This approach replaces unattended installations by using customer.inf files that might have been used in earlier versions (NAC 3.x/4.x).

To create this file, open regedit on a preconfigured machine, export the registry key as given above, and save it as mysettings.reg.

To add components to an already existing installation, use the following commands:

REM uncomment to add Credential Provider to an existing installation (e.g. Single Sign-On)
REM start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN ADDLOCAL=x64CredProv REBOOT=Suppress"

REM uncomment to add Firewall Driver to an existing (VPN-only) installation (e.g. ENA)
REM start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN ADDLOCAL=DrvSPAC REBOOT=Suppress"

REM uncomment to add Credential Provider and Firewall Driver to an existing installation
REM start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN ADDLOCAL=x64CredProv,DrvSPAC REBOOT=Suppress"

NAC 5.x can read CA certificates from the Windows certificate store (folder Trusted Root Certification Authorities), where the desired certificate can be stored.

Step 2. Copy the File to the Setup Directory
  • Copy the silent.cmd file to the folder containing the BarracudaNAC.exe file.
Step 3. Execute the Installation
  • Execute the silent.cmd file to trigger an unattended customer setup.

After installing the client, you can connect and configure the settings. Continue with Getting Started.
