Enable port mirroring for the selected interface as the span destination with the following command:. In the Hardware list, under the Network Adapter drop-down list, select Hardware Acceleration and clear the Virtual Machine Queue option for the monitoring network interface.
Under the Port Mirroring section, select Destination as the mirroring mode for the new virtual interface. Specifies one or more Hyper-V hosts on which the virtual LAN settings on a virtual machine network adapter are to be configured. The default is the local computer. Use localhost or a dot. Specifies one or more user accounts that have permission to perform this action. The default is the current user. Specifies Isolated mode for the virtual machine network adapter to be configured.
Specifies the native virtual LAN identifier for a virtual machine network adapter. Specifies that a Microsoft. See Configuration for details. Netgate Logo Netgate Docs. Note If pfSense software will be used as a perimeter firewall for an organization and the attack surface should be minimized, the best practice is typically to run the firewall non-virtualized on stand-alone hardware.
Click OK to complete the switch setup. Click Next and proceed to the Installation Options step Select Install an operating system from a bootable image file Browse to the pfSense software installer ISO image Click Next to display the summary at the end of the wizard Review the virtual machine information Click Finish if all of the information is correct This completes the wizard but there are several items which must be set on the VM for it to successfully install and boot pfSense software.
For more information, see OT monitoring with virtual appliances. Enter the required size according to your organization's needs select Fixed Size disk type. Specify the memory allocation according to your organization's needs , in standard RAM denomination eg. Do not enable Dyanmic Memory. Configure the network adaptor according to your server network topology.
Allocate CPU resources according to your organization's needs. This guide starts at a point with a Windows and the Hyper-V role installed. If other VMs are already running on Hyper-V, then it is not likely necessary to follow the networking steps too closely. However, skim through it to see what is suggested before building the pfSense software virtual machine part.
Set the Name for the newly added switch to LAN. Set the Name for the newly added switch to WAN. During deployment, if you have a host cluster, you can either provision storage locally on a specific host or on a shared host. Hyperthreading technology allows a single physical processor core to behave like two logical processors.
We recommend that you disable hyperthreading for your systems that run the threat defense virtual. The Snort process already maximizes the processing resources in a CPU core.
When you attempt to push two CPU utilization threads through each processor, you do not receive any improvement in performance. You may actually see a decrease in performance because of the overhead required for the hyperthreading process. Workaround —Edit the virtual machine settings in vSphere to add a serial port while the device is powered off.
Right-click the virtual machine and select Edit Settings. On the Virtual Hardware tab, expand Serial port , and select connection type Use physical serial port. The threat defense virtual uses promiscuous mode to operate, and the performance of virtual machines that require promiscuous mode may be adversely affected if these virtual machines are protected by a distributed firewall. VMware recommends that you exclude virtual machines that require promiscuous mode from distributed firewall protection.
In NSX 6. Move the VMs that you want to exclude to Selected Objects. If a virtual machine has multiple vNICs, all of them are excluded from protection. To exclude the new vNICs from firewall protection, you must remove the virtual machine from the Exclusion List and then add it back to the Exclusion List.
An alternative workaround is to power cycle power off and then power on the virtual machine, but the first option is less disruptive. For a vSphere standard switch, the three elements of the Layer 2 Security policy are promiscuous mode, MAC address changes, and forged transmits. Threat Defense Virtual uses promiscuous mode to operate, and threat defense virtual rtual high availability depends on switching the MAC address between the active and the standby to operate correctly.
The default settings will block correct operation of the threat defense virtual. See the following required settings:.
You must edit the security policy for a vSphere standard switch in the vSphere Web Client and set the Promiscuous mode option to Accept. Firewalls, port scanners, intrusion detection systems and so on, need to run in promiscuous mode.
You should verify the security policy for a vSphere standard switch in the vSphere Web Client and confirm the MAC address changes option is set to Accept. You should verify the security policy for a vSphere standard switch in the vSphere Web Client and confirm the Forged transmits option is set to Accept. If you are observing abnormal behavior such as Snort taking a long time to shut down, or the VM being slow in general or when a certain process is executed, collect logs from the threat defense virtual and the VM host.
If a number of threat defense virtual instances have been created on a single host with insufficient memory and no dedicated CPU, Snort will take a long time to shut down which will result in the creation of Snort cores. On the Manage tab, click Networking , and select Virtual switches.
Select a standard switch from the list and click Edit settings. Accept promiscuous mode activation, MAC address changes, and forged transmits in the guest operating system of the virtual machines attached to the standard switch.
Ensure these settings are the same on all networks that are configured for management and failover HA interfaces on the threat defense virtual devices. You can avoid reboots and configuration issues by planning the threat defense virtual vNIC and interface mapping in advance of deployment. The threat defense virtual deploys with 10 interfaces, and must be powered up at firstboot with at least 4 interfaces.
The threat defense virtual supports the vmxnet3 default , ixgbe, and e virtual network adapters. In addition, with a properly configured system, threat defense virtual also supports the ixgbe-vf driver for SR-IOV; see System Requirements for more information. Threat Defense Virtual on VMware now defaults to vmxnet3 interfaces when you create a virtual device. If you are using e interfaces, we strongly recommend you switch.
The vmxnet3 device drivers and network processing are integrated with the ESXi hypervisor, so they use fewer resources and offer better network performance. The following sections provide guidelines and limitations for the supported virtual network adapters used with threat defense virtual on VMware.
As previously stated, the threat defense virtual deploys with 10 interfaces, and must be powered up at firstboot with at least 4 interfaces. This may lead to issues during HA formation with the secondary threat defense virtual device. You do not need to use all 10 threat defense virtual interfaces; for interfaces you do not intend to use, you can simply leave the interface disabled within the threat defense virtual configuration.
Keep in mind that you cannot add more virtual interfaces to the virtual machine after deployment. The Management interface is a prerequisite for data interface management, so you still need to configure it in your initial setup.
Note that the management center access from a data interface is not supported in High Availability deployments. For more information about configuring a data interface for the management center access, see the configure network management-data-interface command in Cisco Secure Firewall Threat Defense Command Reference. The order of failover having two virtual NICs for the ESX port group, which is used in threat defense virtual inside interface or the failover high availability link, must be configured in a manner where one virtual NIC acts as an active uplink and the other as the standby uplink.
This is necessary for the two VMs to ping each other or for the threat defense virtual high availability HA link to be up. For vmxnet3, Cisco recommends using a host managed by VMware vCenter when using more than four vmxnet3 network interfaces. When deployed on standalone ESXi, additional network interfaces are not added to the virtual machine with sequential PCI bus addresses.
When the host is running standalone ESXi, the only way to determine the order of the network interfaces is to manually compare the MAC addresses seen on the threat defense virtual to the MAC addresses seen from the VMware configuration tool. The following table describes the concordance of Network Adapter, Source Networks and Destination Networks for threat defense virtual for vmxnet3 and ixgbe interfaces.
For 7. Refer to the Intel Technical Brief for more information. If you are upgrading your threat defense virtual to 6. The following table describes the concordance of Network Adapter, Source Networks and Destination Networks for threat defense virtual for the default e interfaces. Management and 7.
Starting with the 6. To change e interfaces to vmxnet3, you must delete ALL interfaces and reinstall them with the vmxnet3 driver. Although you can mix interfaces in your deployment such as, e interfaces on the management center and vmxnet3 interfaces on its managed virtual device , you cannot mix interfaces on the same virtual appliance.
All sensing and management interfaces on the virtual appliance must be of the same type. Power off the threat defense virtual or the management center virtual Machine. Right-click the threat defense virtual or the management center virtual Machine in the inventory and select Edit Settings.
Select the applicable network adapters and then select Remove. Click Add to open the Add Hardware Wizard. Select Ethernet adapter and click Next. Repeat for all interfaces on the threat defense virtual. Power on the threat defense virtual or the management center virtual from the VMware console.
You can have a total of 10 interfaces 1 management, 1 diagnostic, 8 data interfaces when you deploy a threat defense virtual device. For data interfaces, make sure that the Source Networks map to the correct Destination Networks , and that each data interface maps to a unique subnet or VLAN.
If you need more physical-interface equivalents for a threat defense virtual device, you basically have to start over. To successfully deploy the threat defense virtual you should be familiar with VMware and vSphere including vSphere networking, ESXi host setup and configuration, and virtual machine guest deployment. VMware provides several methods to provision vSphere virtual machines. The optimal method for your environment depends on factors such as the size and type of your infrastructure and the goals that you want to achieve.
The vSphere Web Client and the vSphere Client are the primary interfaces for managing all aspects of the vSphere environment. They also provide console access to virtual machines.
All administrative functions are available through the vSphere Web Client. A subset of those functions is available through the vSphere Client. The following flowchart illustrates the workflow for deploying the threat defense virtual on ESXi host. Optional Disable Hyperthreading : Disable hyperthreading for your systems that run the threat defense virtual. Management Center or Device Manager. The following flowchart illustrates the workflow for deploying the threat defense virtual on vSphere vCenter.
Use this procedure to deploy the threat defense virtual appliance to VMware vSphere vCenter. You must have at least one network configured in vSphere for management before you deploy the threat defense virtual.
