With the manager software, you can also create and upload
configuration files (which, in turn, can be used as a base for any
number of servers), download new firmware, and display statistics
and event logs. You’re also given easy access to self-explanatory
configuration and network diagnostic information.
Once installed and configured, the management software
automatically locates all
Remote Access Servers
and displays then in a
Server List window. Simply point and click to access a particular server.
Dynamic Host Configuration Protocol (DHCP) enables you to manage
IP addresses and other IP-related options from a single location. It’s
easy to carry out remote or local management functions from
anywhere on your network.
You can also manage the server directly from its front-panel
LCD and keypad. The display can be viewed in multiple languages,
and you use the keypad to choose your type of Ethernet connection.
Extensive security
The
Remote Access Server
also features built-in, multilevel
Windows NT Domain Server Authentication security that protects
your network from unauthorized access. In addition to individual
user-name and password protection, the server supports fixed dial-
back confirmation and major security standards. Along with Windows
NT Domain Server, it supports PAP, CHAP, NetWare Bindery, PassGo
Defender, and SecurID-ACE/Server. Its packet filtering feature enables
the
Remote Access Server
to accept or reject incoming data packets
according to the filter definitions you set. This can also be done with
a RADIUS security server.
