This section contains general recommendations and explains some common
problems that can occur with common Web browsers, the Nortel VPN Router Web
Manager, and the VPN Router.

If you have a problem browsing the Nortel VPN Client Manager, start by checking
the following recommendations to ensure that you are using the correct Web
browser version and settings. For additional troubleshooting, check the described
Web browser problems and solutions, error messages, and tips described later in
this section.
Nortel VPN Client Manager uses Java* and HTML features. For the management
interface to function properly, verify that your Web browser meets the following
minimum requirements:
• Platforms supported include Windows 95, Windows 98, Windows NT, or
Macintosh*.
• Display setting of 256 colors or greater.
• Browser versions supported include Microsoft Internet Explorer, Version 4.0
or later and Netscape Communicator*,Version 4.0 or later. Not using a recent
version of Internet Explorer causes the upper-left corners of the management
windows to remain gray rather than displaying the navigational menu and the
current menu selection, respectively.
