 ## Manually adding a firewall entry
 
-As outlined above, direct mode requires that your personal firewall allow **vsls-agent** to accept connections in the port range 5990-5999. If you want to use direct mode but have found that your firewall does not have vsls-agent entry, you can add it manually. How you do this will vary by firewall software, but you can find information about **[configuring the Windows Firewall here](/windows/security/threat-protection/windows-firewall/create-an-inbound-program-or-service-rule)**.

 ## Proxies

While automatic proxy settings should work on Windows, when using macOS or Linux (and with certain proxy configurations on Windows) the **HTTP_PROXY** and **HTTPS_PROXY** environment variables will need to be set *globally* for VS or in *Application > Proxy* settings for VS Code.

+Note: if the proxy is not configured in VS Code's *Application > Proxy* settings it will also be inherited from the http_proxy and https_proxy environment variables.
 
 If your proxy doesn't automatically set these for you, you can manually set the variables in the following form:
