email or triggers. The firewall automatically detects and
combats a range of denial of service attacks including SYN
and FIN flooding, Ping of death, Smurf attacks and port
scans.

IPsec-compliant security services.

Calling Line Identification (CLI), which uses the ISDN
address of the incoming call to verify that the caller is calling
from an authentic location.

ISDN callback, which verifies the caller using CLI, disconnects
the incoming call, then calls the destination back to establish
the link. This allows a remote site to reverse the call charges
to a central office, for central billing of ISDN calls.

PAP and CHAP to authenticate remote access using
passwords and user names.

TACACS and RADIUS for authenticating users. The AR720
can query TACACS or RADIUS servers running on a
network host to authenticate users. A centralised database
simplifies management of a large user population.

Protect Your Data with Powerful DES Encryption

If you are transmitting sensitive information, such as cost
estimates, product plans, and investment opportunities across
the Internet you want to secure this data so that it is
indecipherable to all but the intended recipients. AT-VPNet
provides powerful DES or 3DES encryption. Your data is
scrambled before it is transmitted across the Internet, making
the data meaningless if intercepted. Only the data portion of
the IP packet is encrypted; the address information required for
routing the packet to its destination is unchanged. AT-VPNet
uses a separate daughter card that fits inside the AR720 to
offload the processor-intensive task of data encryption, so
routing performance is not affected.

Note: The export of strong DES-based cryptography such as AT-VPNet
is subject to export controls in most countries. Contact your distributor
or reseller for details.

THE AR720  FEATURE  SET

The following are just some of the features provided by
the AR720:

Wide-area networking via Frame Relay, Point-to-Point
Protocol, and X.25.

Basic Rate and Primary Rate access to Integrated Services
Digital Network (ISDN) services, with dial on demand,
bandwidth on demand and channel aggregation facilities.

Multiprotocol routing, including TCP/IP, Novell® IPX,
DECnet™, AppleTalk® and GRE (

Generic Routing

Encapsulation

) protocols. Supported routing protocols include

RIP and RIP v2, EGP, OSPF,  and Novell® RIP and SAP.

Terminal server.

Bridging.

Backup server for leased line, PSTN and ISDN.

LPD and Streams print server for network-wide printing.

Advanced packet filtering for IP, Novell® IPX and DECnet™.

Frame Relay over synchronous and ISDN links, with logical
interfaces, congestion control and a slowstart mechanism.

Bandwidth management, multilink PPP channel aggregation,
network on demand and bandwidth on demand.

Hardware-based data encryption and compression.

Traffic shaping and Quality of Service (QoS) with the
Resource Reservation Protocol (RSVP) and Bandwidth
Allocation Control Protocol (BACP).

X.25 communications server.

TDM (Time Division Multiplexing).

Automated network monitoring and control with a
sophisticated, configurable event logging facility.

Triggers for automatic and timed execution of commands,
and scripting for automated configuration and centralised
management of configurations.

Support for the Simple Network Management Protocol
(SNMP) allows the router to be managed by a separate
network management station.
