# Use TD Toolbelt behind a proxy You can configure TD Toolbelt to use a proxy by setting environment variables in your shell. Set the `HTTP_PROXY` environment variable. Proxy support is available in TD Toolbelt version v0.10.41 and later. ```powershell $env:HTTP_PROXY = "http://proxy_host:proxy_port" $env:HTTPS_PROXY = "https://proxy_host:proxy_port" ``` ```bash export HTTP_PROXY=http://proxy_host:proxy_port export HTTPS_PROXY=https://proxy_host:proxy_port ``` You can set the user and password for proxy authentication in this format: `user:passwd@proxy_host:proxy_port` ## Troubleshooting If you do not want to run the above commands every time, for Windows, you can set the environment variable, and for Linux and other platforms, you can set it in your `.bash_profile` file.
