Note: We are using Opera 30.0 to demonstrate the changes, but these steps should be similar for all versions of Opera.
Follow these instructions to configure Opera to use a Proxy Server:
Open the Opera menu in the top left corner and click on Settings.
A new tab will open with your Setting's menu. Scroll down to Network and click on Change proxy settings.
In the Connections tab click on LAN settings.
This will display the Local Area Network (LAN) Settings window.
Uncheck the box for Automatically detect settings and check the box for Use a proxy server for your LAN. Enter your proxy server into the Address box and click OK.
In the Address field, enter the IP Address of your Proxy Server, and the Proxy Server Port Number in the Port field. You will receive the IP Address and Port Number of your Proxy Server(s) in a separate email.
Press the OK button and then press OK again to save your settings.
Now when you surf, you will be surfing by using the Proxy Server. The first time you surf, depending on your account's authentication settings, you may be asked to enter your credentials, which were supplied in your Welcome Email.
To stop using the Proxy Server, repeat the above steps, but uncheck the Use a proxy server for your LAN box.
