VPN 3002 Hardware Client User Guide
HTTPS is often confused with a similar protocol, S-HTTP (Secure HTTP), which encrypts only HTTP
application-level data. SSL encrypts all data between client and server at the IP socket level, and is thus
more secure.
SSL uses digital certificates for authentication. The VPN 3002 creates a self-signed SSL server
certificate when it boots, and this certificate must be installed in the browser. Once the certificate is
installed, you can connect using HTTPS. You need to install the certificate from a given VPN 3002 only
once.
Managing the VPN 3002 is the same with or without SSL. Manager screens may take slightly longer to
load with SSL because of encryption / decryption processing. When connected via SSL, the browser
shows a locked-padlock icon on its status bar. Both Microsoft Internet Explorer and Netscape Navigator
support SSL.
For HTTPS to work on the Public interface, you must enable HTTPS on the VPN 3002 through the CLI
or from an HTTP session on the Private interface first. See
Follow these steps to install and use the SSL certificate for the first time. We provide separate
instructions for Internet Explorer and Netscape Navigator when they diverge.
1 Connect to the VPN 3002 using HTTP as above.
2 On the login screen, click the
Install SSL Certificate link.
The Manager displays the
Install SSL Certificate screen and automatically begins to download and install
its SSL certificate in your browser.

The installation sequence now differs depending on the browser. Continue below for Internet Explorer,
or skip to Installing the SSL certificate with Netscape on page 1-9.
Installing the SSL certificate with Internet Explorer
This section describes SSL certificate installation using Microsoft Internet Explorer 5.0. (With Internet
Explorer 4.0, some dialog boxes may differ but the process is similar.)
