# Configure proxy settings during AWS IoT SiteWise Edge gateway installation
<a name="manage-trust-stores-proxy_config"></a>

You can configure AWS IoT SiteWise Edge to work with a proxy server during gateway installation. The installation script supports both HTTP and HTTPS proxies and can automatically configure trust stores for secure proxy connections.

When you run the installation script with proxy settings, it performs several important tasks:
+ Validates the proxy URL format and parameters to ensure they are correctly specified.
+ Downloads and installs required dependencies through the configured proxy.
+ If a proxy CA certificate is provided, it's appended to the AWS IoT Greengrass root CA certificate and imported into the Java KeyStore.
+ Configures AWS IoT Greengrass (which SiteWise Edge uses) to use the proxy for all outbound connections.
+ Completes the SiteWise Edge installation with the appropriate proxy and trust store configurations.

**To configure proxy settings when installing gateway software**

1. Create a SiteWise Edge gateway. For more information, see [Create a self-hosted SiteWise Edge gateway](create-gateway-ggv2.md) and [Install the AWS IoT SiteWise Edge gateway software on your local device](install-gateway-software-on-local-device.md).

1. Run the installation script with the appropriate proxy settings for your environment. Replace the placeholders with your specific proxy information 

   Replace each of the following items:
   + `-p`, `--proxy-url` – The URL of the proxy server. The URL must be either `http` or `https`.
   + `-n`, `--no-proxy` – A comma-separated list of addresses to bypass the proxy.
   + (Optional)`-c`, `--proxy-ca-cert` – Path to the proxy CA certificate file.
   + (Optional)`-j`, `--javastorepass` – The Java KeyStore password. The default password is `changeit`.

#### [ Linux ]

   For Linux systems, use the following command structure:

   ```
   sudo ./install.sh -p {{proxy-url}} -n {{no-proxy-addresses}} [-c {{proxy-ca-cert-path}}] [-j {{javastorepass}}]
   ```

------
#### [ Windows ]

   For Microsoft Windows systems using PowerShell, use this command structure:

   ```
   .\install.ps1 -ProxyUrl {{proxy-url}} -NoProxyAddresses {{no-proxy-addresses}} [-ProxyCaCertPath {{proxy-ca-cert-path}}] [-JavaStorePass {{javastorepass}}]
   ```
