The Proxy Server Options tab of the options dialog in the Manual-Activator appears in the following image:

 

Using this tab you can configure the Manual-Activator to send requests to the CheckPoint License Server through a proxy server.  If you do use a proxy, check the "Use HTTP proxy server..." checkbox and enter the name or IP of the proxy server on your network and the port it uses (most proxy servers operate on a default port of 8080 but this can be changed).

Basic authentication is also supported.  If your proxy server uses basic authentication then check the "proxy server uses authentication" check box and enter your user name and password.
