Some network topologies require an upstream web proxy server. On the Web Protection > Web Filter Profiles > Parent Proxies page you can configure a parent proxy.
To configure a parent proxy, do the following:
Click New Parent Proxy.
The Add Parent Proxy dialog box opens.
Make the following settings:
Name: Enter a descriptive name for this parent proxy.
Comment (optional): Add a description or other information.
Use Proxy for These Hosts: Add hosts to this box for which the parent proxy is to be used, e.g. *.wikipedia.org. Note that you can use pattern matching here. Regular expressions, however, are not allowed. If you leave the box empty, an asterisk (*) is automatically added when clicking Save, which matches all hosts. Such a proxy definition can therefore be regarded as a fallback proxy which matches when none of the other proxies, if existent, do.
Parent proxy: Select or add the network definition of the parent proxy.
Port: The default port for the connection to the parent proxy is 8080. If your parent proxy requires a different port, you can change it here.
Proxy requires authentication: If the parent proxy requires authentication, select the checkbox and enter username and password in the appearing textboxes.
The new parent proxy appears on the Parent Proxies list.
The proxy can now be used in filter actions or globally.
