This page gives information exceptions that might need to be manually added to your firewall settings.


Overview


Chaos products add various exceptions (rules) for themselves during the installation process. Sometimes, adding a firewall exception isn’t enough to allow an application to receive information. In these cases, the only way to get the program operating correctly is to manually add a port/program exception to your firewall.

Manual changes to firewall exceptions are made through your OS settings. The procedure for adding a firewall exception varies for each OS. Please refer to your OS documentation for steps on how to manually set an exception for a specific executable or port in your OS.


Chaos License Server


During installation, exceptions are made to your firewall to ensure smooth running. The exceptions are added for:

C:\Program Files\Chaos\VRLService\OLS\vrol.exe

C:\Program Files\Chaos\UnifiedLogin\ula.exe

After installing the License Server, you need to ensure that TCP Port 30304 is open for both incoming and outgoing communications in the firewall software running on the machine where the license server is installed.

Firewall exceptions are necessary for running the Chaos License Server locally. If you have disabled the Add firewall exception option in both the Chaos product - and the License Server installers, we recommend you re-install, while making sure the option is enabled.

Otherwise, you can add the exception manually:

  1. Open the Windows Start Menu and choose Control Panel.
  2. Search for "Windows Firewall".
  3. Select Allow a program or features through Windows Firewall.
  4. Click on Allow another program.
  5. Browse to the install location of the license server. By default, it is in C:\Program Files\Chaos\VRLService\OLS\.
  6. Add vrol.exe
  1. From the Apple menu, choose System Preferences.
  2. Go to Security or Security & Privacy.
  3. Click the Firewall tab.
  4. Unlock the pane by clicking the lock icon in the lower-left corner and type in your account's credentials (you'll need administrator privileges).
  5. Select Advanced and click the plus sign.
  6. Browse to the install location of the license server. By default, it is in Applications > Chaos> VRLService > OLS.
  7. Select vrol.bin

V-Ray for Max/Maya/Nuke and Standalone


During the installation process of V-Ray Standalone on Windows or macOS, V-Ray adds a firewall exception on the executable. The exception is added for:

Windows - C:\Program Files\Chaos Group\V-Ray\Standalone for x64\bin\x64\vc11\vray.exe

macOS - /Applications/ChaosGroup/V-Ray/Standalone_for_mavericks_x64/bin/mavericks_x64/gcc-4.2/vray.bin

Linux - /usr/ChaosGroup/V-Ray/Standalone_for_linux_x64/bin/linux_x64/gcc-4.4/vray.bin

In the case of 3ds Max and Maya in Windows or macOS, an exception may also be added for spawner executables vraystdspawner.exe and vraymayaspawner.exe.

In the case of 3ds Max, for Windows, it is installed in:
C:\Program Files\Chaos Group\V-Ray\3ds Max 20XX\bin

In the case of Maya, it depends on the OS, but it is always where Maya is installed.

Windows - C:\Program Files\Autodesk\Maya20xx\vray\bin\vray.exe

macOS - /Applications/Autodesk/maya20XX/vray/bin/vray.bin

Linux - /usr/autodesk/maya20xx/vray/bin/vray.bin

In the case of Nuke, vray.exe is installed in a subfolder of the Nuke installation.

Windows - C:\Program Files\Nuke<ver>\plugins\vray\vray.exe

Linux - /usr/local/Nuke<ver>/plugins/vray/vray.bin

V-Ray's Linux installers do not attempt to create any firewall exceptions. Firewall exceptions can be added manually in Linux for vray.bin.


V-Ray for Rhino/Revit and SketchUp


During the installation process of V-Ray for Rhino and V-Ray for SketchUp, V-Ray sets a firewall exception for the executable for V-Ray 3.4 NeUI.

SketchUp: C:\Program Files\Chaos Group\V-Ray\V-Ray 3.4 for SketchUp\extension\vrayneui-win32-x64\vrayneui.exe

Rhino: C:\Program Files\Chaos Group\V-Ray\V-Ray 3.4 for Rhinoceros 5\vrayneui-win32-x64\vrayneui.exe

During the V-Ray for Revit installation, V-Ray adds an exception on the executable for the Standalone Material Editor:

C:\Program Files\Chaos Group\V-Ray\V-Ray 3.5 for Revit\vrmateditor\vrmateditor.exe

For all three programs, V-Ray adds firewall exceptions on port 20208 (the default port we use for V-Ray Standalone), on both TCP and UDP,


V-Ray Swarm


During the Swarm installation, V-Ray adds a firewall exception for the executable for swrm.exe:

C:\Program Files\ChaosGroup\V-Ray Swarm\swrm.exe

V-Ray also adds firewall exceptions on port 24267 for access to the Swarm Web interface.
