 * I use Wordfence on a website that sits behind a proxy server that needs additional
   NTLM authentication to connect to external websites or IPs. As the optimized 
   Firewall uses an own http-library (and is loaded before wordpress), i think it
   doesn’t use the curl-actions and filters provided by wordpress or the authentication
   username / Password Constants defined in the wp-config.php. How can i get the
   wordfence optimized firewall to use the correct proxy settings for connecting
   to external ips/websites?

 * Excuse me, miswrote a little detail: the proxy requires BASIC authentication,
   not NTLM.

 * Hi [@kuchenundkakao](https://wordpress.org/support/users/kuchenundkakao/)
 * Please send your Wordfence diagnostics report.
 * Update to the latest version of Wordfence if you haven’t already done so.
 * Go to the top of the “**_Diagnostics_**” tab on the Wordfence “**_Tools_**” page.
   There will be a “**_SEND REPORT BY EMAIL_**” button to send the diagnostics report.
   Enter **_wftest [at] wordfence [dot] com_** as the email and **_kuchenundkakao_**
   as the forum username please.
 * **_Once you have emailed me the diagnostics report can you reply here to let 
   me know that it has been sent. This is important in the unlikely event that your
   installation of WordPress is having an issue with sending mail_**
