VPN 3000 Concentrator Series User Guide
Configuration | System | Management Protocols | HTTP/HTTPS
This screen lets you configure and enable the VPN Concentrator’s HTTP/HTTPS server: Hypertext
Transfer Protocol and HTTP over SSL (Secure Sockets Layer) protocol. When the server is enabled, you
can use a Web browser to communicate with the VPN Concentrator. HTTPS lets you use a Web browser
over a secure, encrypted connection.
Notes: The VPN Concentrator Manager requires the HTTP/HTTPS server. If you click
Apply, even if you have
made no changes on this screen, you will break your HTTP/HTTPS connection and you must restart the
Manager session from the login screen.
If you disable either HTTP or HTTPS, and that is the protocol you are currently using, you can reconnect
with the other protocol if it is enabled and configured.
If you disable both HTTP and HTTPS, you cannot use a Web browser to connect to the VPN
Concentrator. Use the Cisco Command Line Interface from the console or a Telnet session.
Related information:
• For information on installing the SSL digital certificate in your browser and connecting via HTTPS,
see Chapter 1, Using the VPN 3000 Concentrator Series Manager.
• To configure SSL parameters, see the
Configuration | System | Management Protocols | SSL screen.
• To install, generate, view, or delete the SSL certificate on the VPN Concentrator, see the Administration
| Certificate Management
screens.

Enable HTTP
Check the box to enable the HTTP server. The box is checked by default. You must enable HTTP to
install the SSL certificate in the browser initially, so you can thereafter use HTTPS. Disabling the HTTP
server provides additional security, but makes system management less convenient. See the notes above.
