Security

Security on network devices is a major concern for almost anyone with
a network. The Express 6100/6120 provides many tools for securing
the local network from hostile users. Connections can be authenticat-
ed using passwords. A RADIUS client can also be used.

The Telnet and web browser configuration can also be protected using
the same authentication methods. Each menu item in the Express
6100/6120 has a security level associated with it. A Telnet session is
assigned a privilege level which determines which menu items are ac-
cessible to the Telnet client. See Security Levels on page 3-7 for more
information on menu security levels.

Filters can be defined to prevent certain addresses or protocols from
being transferred from LAN-to-WAN, WAN-to-LAN, or WAN-to-
WAN.

As already mentioned, a web browser can be used to configure the Ex-
press 6100/6120. This is accomplished by entering http://10.0.0.1 on
any Windows Internet Explorer browser. If the Express 6100/6120’s IP
address has been changed from the factory default, then 10.0.0.1
should be replaced by that address.
