Configuring HTTP Administrative Connections in ScreenOS Devices Using NSM Overview
You can configure the following options for administrative connections that use HTTP:
Idle time for Web UI management—The number of seconds that the HTTP connection remains idle (no traffic is flowing) before the device drops the connection.
Port number—The default HTTP port number is 80. If you are running HTTP services on a different device port, enter that port number here.
Additionally, the device administrator must use a permitted IP address to initiate an HTTP connection to the device, and the Web service option must be enabled for the interface that the device administrator connects to on the device.
To secure HTTP administrative traffic, you can use the Secure Sockets Layer (SSL) protocol.
