2. In the left pane, choose General, and then Network Connection.
   The Network Connection page appears.
   

   

3. Select Active Provider.
   If proxy settings are specified in the Internet Options of Windows, Native is selected as Active Provider. Click the OK button.
   If you want to specify values that are different from the proxy settings in Internet Options, select Manual as Active Provider, and then set the values as described from step 4. onwards.
   
4. Select HTTP in the Proxy Entries, and then select the Edit button.
   The Edit Proxy Entry window appears.
   
5. Enter Host, Port and Authentication, and then click the OK button.
   The control returns to the Network Connection page.
   
6. Click the Apply button or the OK button.
   The settings are saved.
