Support will help with Untangle configuration but configuration of the virtualization hypervisor is beyond the scope of Untangle support. Untangle wants you to have a successful deployment.
Unfortunately, our support staff doesn't have the expertise in VMware ESX to ensure that we can help you with installing and configuring VMware. We will certainly help you with your Untangle configuration, provided it's running on ESX. That being said, we'd like to make you aware that systems like Untangle that require a lot of real time processing aren't great candidates for virtualization.
VMware works by "time-slicing" the physical CPUs in the host system. While the VMware server is off processing other virtual machines, the Untangle server is unable to process traffic. At the same time, network traffic continues to arrive. This traffic stacks up and presents itself to the Untangle VM as "bursty.
The exact threshold of where it will be unsuitable is hard to say. It is a combination of traffic level, types of traffic, and user expectations. Do not specify a gateway or any other information, and click OK. Appliance on a Windows VMware Host Note: Fewer steps are required to force routing through the Untangle server for hosts configured in Production mode. Since VMnet2 and VMnet3 will not show up in your Windows network connections, you will need to know which network each of your Local Area Network Connections is connected to i.
External, Internal, and DMZ. If you have set up your Windows based VMware host in production mode, you must choose only one of the bridged network connections to be used for your Windows host. These will show up as various Local Area Connections such as:.
In this example, our Local Area Connection 4 is connected to our Internal network. To force routing via the physical connection of Local Area Connection 4 we use another example. Linux varies a bit from distribution to distribution. Until we have complete instructions available for the different distributions, we will use bash to accomplish the task.
Setting up networks on Linux hosts requires root access to the command line. If you are comfortable using different shells in Linux, feel free to translate as necessary on-the-fly as the basic commands should be identical.
IP from it. If not, something went wrong. Note: If you have configured the Production Virtual Server you can substitute vmnet2 with the appropriate physical network card that is connected to your Internal or DMZ network. All rights reserved. Please contribute if you find this software useful.
With this we can confirm that To make these changes permanent on your Linux host, you will need to use the appropriate tools or write yourself a script that takes care of things for you. If you performed this changes as we did here, rebooting your Linux host will revert all of the settings.
Look us up in IRC if you need help with your specific situation. Applies to Windows and Linux Hosts Depending on your hardware and software configuration, you may experience potentially insane clock drift issues in your Untangle VM. This is a common situation shared with all Linux Virtual Machines when the guests differ enough from their host machines regardless of whether the host is running a Windows or Linux based operating system. This section is dedicated to identifying and resolving such issues.
We recommend you make these changes on all Untangle VMware machines. This problem is easily identified once you check the date and time on your Untangle VM as the time will be incorrect after you have set it. You will want to make sure time is being kept properly within any Untangle VM as the Untangle VM uses many time based policies for filtering traffic.
It is important that your host has and keeps good time as well. To verify if you have a clock synchronization issue, do the following:. We recommend that you make sure the VMware time synchronization to host is enabled as a best practice.
If you downloaded the Untangle VMware zip file, proceed immediately to Step 6. Regardless of symptoms, we recommend that you use VMware tools to syncronize the time with the host OS. Once you have verified that the host time is correct and good you can follow these steps to enable VMware tools clock syncronization. Untangle VMware downloads prior to and including 5.
All Untangle VMware images newer than version 5. Need Screenshots? Alternatively, if you have a local console available for your Untangle VM, you can enable time synchronization as follows:.
VMware tools should be installed by default if you downloaded the Untangle VMware zip file; however, if you created your own VMware machine or have a need to upgrade the VMware tools, you will need to install VMware tools as follows: More details to follow but since they are pre-installed on the download….
The Untangle gateway relies on accurate time for time-based policies and filtering policies. VMware Tools uses a slow adjustment to correct for time differences. As a result we recommend you reboot to get a quick correction and let VMware Tools take it from there. Future versions of Untangle are not expected to have these issues as the underlying kernel issues are normalizing over time; however, using VMware Tools is probably a best practice that you should stick with.
