Some features of Oracle Reports Services support retrieving or sending information through a firewall. For example, the URL engine, the XML data source, the Text data source, and the mail destination features all retrieve or send information through the firewall. For these features to function properly, Reports Server requires certain proxy information.
To specify proxy information:
Navigate to the Reports Server or Reports Application Home page (see Section 6.3, "Viewing the Component Topology").
From the Reports menu, select Administration > Advanced Configuration.
The Advanced Configuration page displays.
On the Advanced Configuration page, set proxy hosts and ports available for various protocols, such as
file. You can also specify the addresses for which proxies can be bypassed.
