The PingAccess Hostname and Port might not be the actual host and port that policy server is listening to, depending on the network routing configuration and network elements, such as reverse proxies and load balancers. The PingAccess Host and Port are where the agent sends its requests. For example, if you have a cluster of engines behind a load balancer, the PingAccess Host and Port values might point to the load balancer rather than directly to an engine host. This configuration provides fault tolerance for the agent connectivity. | > | **Failover Host** | No | In the **Failover Host** fields, enter the **Hostname** and **Port** of the PingAccess server where the agent should send requests in the event of a failover from the **PingAccess Host**. Additional failover hosts can be added using the application programming interface (API). | > | **Agent Trusted Certificate** | Yes | Select a certificate to export in the `_agent.properties` file. The agent uses this certificate to communicate with the PingAccess engine using Secure Sockets Layer (SSL) *(tooltip: \
\

A protocol for authenticated and encrypted links between networked machines, typically over HTTPS. SSL was deprecated in 1999 in favor of Transport Layer Security (TLS).\

\
)*/TLS.PingAccess determines the certificates that are available to select in this list based on the certificates that have been imported into PingAccess. If the certificate you want to use isn't available, you must import it into the system. Learn more in [Importing certificates](pa_importing_certificates.html). You must specify the certificate authority (CA) root certificate if the agent listener presents a CA-signed certificate chain.The default value is `C=US, O=Ping Identity, CN=localhost (Generated: AGENT)`. | To configure advanced settings, click **Show Advanced**. > **Collapse: Advanced fields** > > | Field | Required | Description | > | -------------------------------------------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | > | **Override Request IP Source Configuration** | No | When enabled, the configuration you provide in the following fields overrides the default IP source settings (defined in **Settings > HTTP Requests > IP Source**) for this agent instance.![Screen capture of the Override Request IP Source Configuration field.](_images/override_request_ip_source_config.png)To configure the agent to use different Internet Protocol (IP) *(tooltip: \
