Configuring the Firewall to Allow Agent Access - LoadRunner

You modify your firewall settings to enable communication between the machine(s) inside the firewall and machines outside the firewall.

TCP configuration

The LoadRunner agent tries to establish a connection with the MI Listener using port 443. To enable this connection, allow an outgoing connection for HTTPS service on the firewall for port 443. As a result, the agent will keep trying to connect to the MI Listener at an interval of the number of seconds specified in the Connection Timeout field in the agent configuration. Then the MI Listener connects back to the agent. From this point on, the agent listens to commands from the MI Listener.

HTTPS configuration

The LoadRunner agent tries to establish a connection with the MI Listener using the proxy port specified in the Proxy Port field. To enable this connection, allow an outgoing connection for HTTPS service on the firewall for port 443. The agent will keep trying to connect to the MI Listener at an interval of the number of seconds specified in the Connection Timeout field in the agent configuration. On successful connection, the agent on the proxy server connects to the MI Listener, and the MI Listener connects back to the agent through the proxy server. From this point on, the agent listens to commands from the MI Listener.

Note: You can connect the Controller to load generators over a firewall without using the MI Listener and LoadRunner agent. To do so, open port 54345 on a firewall in the Controller’s LAN and in the load generator’s LAN to allow incoming and outgoing data.
