# Run Vusers over a firewall

You can configure Vusers to run over a firewall.

In this topic:

## Run Vusers over a firewall - workflow

Before you configure your system to run Vusers over the firewall, ensure that you have completed the configuration steps described in Initial configuration of over firewall system.

The general flow to run Vusers over a firewall is:

1. Specify MI Listener details in the Admin area.

2. Configure the agent on the load generator machine.

3. Configure the load generator host in the Admin area.

To run Vusers over a firewall:

1. In Administration, specify the details of the MI Listener used to run Vusers over the firewall. For details, see Specify MI Listeners.

2. Configure the LoadRunner Agent on each Load Generator machine that runs over a firewall to communicate with the MI Listener.

   For information on how to configure the agent, see Configure the agent.

   Note: After you configure the agent on the Load Generator machine, you can edit the configuration settings from Administration. For details, see Manage hosts in the OpenText Enterprise Performance Engineering Help Center.

3. In Administration, configure the relevant Load Generator hosts to run over a firewall. For details, see Configure hosts to run Vusers over a firewall.

## Configure hosts to run Vusers over a firewall

To use a host to run Vusers over a firewall, you need to configure the relevant hosts as Load Generators in Administration.

Part of the process of configuring a host involves selecting a location for your host. For example, locations can be defined according to physical areas. The location also determines whether the host is located over a firewall.

Before you configure the host, you need to ensure that you have added a location over a firewall. When you are configuring a host to operate over a firewall, you select a location that is located over a firewall.

This section describes the basic steps to add a host as a Load Generator for running Vusers over a firewall. For details about creating hosts, see Add a host.

To configure a host to run Vusers over a firewall:

1. Add the location that is over a firewall.

1. In Administration, select Maintenance > Hosts and click the Locations tab.

2. Click the Add button . The New Location dialog box opens.

3. Enter the following details.

   UI Elements | Description
   --- | ---
   Location Name | The name of the host location. The name must have a logical connection to the host location.
   Description | A description of the host location.
   Over Firewall | Indicates whether the host location is over a firewall.

2. Add the over firewall host.

1. On the Administration sidebar, select Maintenance > Hosts.

2. Select the Hosts tab, and then click the Add Host button .

3. In the New Host dialog box, enter the following details.

   UI Elements | Description
   --- | ---
   Host Name | The fully qualified domain name or IP address of the host that is assigned when creating the host.
   Description | A description of the host.
   Purpose | Select a purpose for the host. Note that a host over a firewall can only have a Load Generator purpose.
   Source | Select the host's source: Local if the host exists in your testing lab, or Cloud if the host was provisioned from a cloud provider.
   Priority | A rank assigned to the host. Assigning a higher priority to a host increases the likelihood of the host being allocated to a test. There are a number of criteria to consider when assigning priority. The main considerations are whether the host is a dedicated machine or a shared resource, and the type of hardware installed on the machine.
   Status | Indicate the status of the host.
   Location | The location of the host that is over the firewall.
   Installation | Select the installation type of the host. For a standalone installation of the Load Generator, select OneLG.
   MI Listener | Enter the IP address or host name of the MI Listener that enables data collection.
   Enable SSL | Indicates whether the Load Generator is to communicate with the Controller using TLS (formerly SSL) or not. This option is available when the load generator is located over a firewall. Note: The load generator uses TLS to communicate with the Controller during runtime only. For non runtime functionality (including collating results), the Load Generator does not use TLS as the communication protocol.
   Belongs to Pools | The host pools to which the host is assigned. Host pools enable you to control which hosts are allocated to which projects.
   Host Attributes | Attributes of the host. Example: Memory, strength, installed components
