Introducing the AR725 Router
Congratulations on purchasing an AR725 Modular Enterprise
Router—the ideal unit for high throughput, fast-response
applications in the larger branch office, or corporate site.
This guide will introduce you to the AR725 router and guide
you through the most common uses and applications. Getting
started will not take long—many applications can be set up in
just a few minutes. If you have any questions about the AR725
router, contact your local distributor or reseller.
CONNECTIVITY OPTIONS
The AR725 supports a wide range of network interfaces so
you can choose the network service that is right for you. The
base unit has two 10/100 autosensing Ethernet ports and two
RS232 asynchronous ports. Additional interfaces can be added
by installing any of the following PICs (
Port Interface Cards
) in
the two expansion bays:

WHAT CAN THE AR725 DO FOR YOU?
Connect You to the Internet
The AR725 router provides you with high speed, unrestricted
access to the Internet. Advanced compression techniques
together with ISDN channel bundling mean that graphic
downloads simply speed along. An intelligent traffic sensor
automatically disconnects the ISDN call if there is no data to be
sent or received, so call charges are minimised. The AR725
supports advanced features that make it easy for your Internet
Service Provider to dynamically assign your Internet address
every time you surf the net.
Connect Regional and Branch Offices to the
Corporate Network
Many small offices and home offices require fast and efficient
access to a central office, to check email, access a database or
download a file. The AR725 supports Windows
®
, Novell
®
and
Apple
®
Macintosh
®
systems. The intelligent bandwidth
management facility automatically opens more ISDN channels
when extra capacity is required, and closes them when traffic
levels reduce. Powerful firewall features protect against
unauthorised access, and break-in attempts can be logged for
later analysis. If your office LAN utilises private IP addresses not
registered on the Internet, the AR725 can translate these private
addresses to a single registered IP address for communication
across the Internet, saving you the time and expense of assigning
registered IP addresses to each device on your LAN.
Connect You to Other Trading Partners
The AR725 allows companies to communicate with other
trading partners using ISDN BRI and PRI circuits, Frame Relay
or X.25, PSTN, Leased Line and Ethernet connectivity.
Information such as reports, quotes and orders can be
transferred between the two offices. The AR725 does not place
any limits on the number of network users, so it will continue
to support you as your business grows.
Connect Teleworkers and Dial-in Users
The AR725 supports dial-in connections via external modems.
Teleworkers and mobile users can dial into an AR725 router at
their local office and access information, read email, download
files and connect to the Internet. Combine dial-in services with
AT-VPNet to provide teleworkers and mobile users with
secure access to the corporate network. External modems can
be used to provide network connections for extra bandwidth
at peak times or to backup ISDN, Frame Relay or leased lines.
Protect Your Network from Unauthorised Access
When you connect to the Internet you have unrestricted
access to the World-Wide Web. Likewise, it has access to you!
To ensure that only authorised users can access your local
network, the AR725 has an extensive range of security
measures, including:
•
A fully featured stateful inspection firewall which dynamically
filters traffic flows based on manager-defined rules. All firewall
events are logged to the router’s Logging Facility, and
