This page gives information exceptions that might need to be manually added to your firewall settings.
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, an exception for the Chaos License Server to your firewall. The exception is added for:
C:\Program Files\Chaos Group\VRLService\OLS\vrol.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.
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
And 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,
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.
