ADSL bridge/router w/ integral 4x 10/100Mbps Switch
High Bandwidth Access to the
Internet and Corporate LAN
The AT-AR256E is the perfect solution for the
small office or branch office that wants to use
high speed, ‘always on’ ADSL services to access
the Internet or other corporate locations.
Combining a ADSL modem, IP router, 4-port
10/100TX switch and Stateful Inspection
Firewall into one affordable unit, the AT-AR256E
provides the ideal solution for bandwidthhungry
end-users and ADSL service providers
who need security. The AT-AR256E is easily
installed over an existing analog line, supporting
standard POTS operation together with stateof-
the-art ADSL services. Applications include
data intensive office use, fast web download,
video-on-demand, video streaming and
telecommuting via Virtual Private Network
(VPN). VPN operation is supported using
IPSec, PPTP and L2TP pass-through.
Business-class Stateful Inspection
Firewall with Intrusion Detection
Because ADSL offers an ‘always on’ connection,
users are actually more at risk using this service
than with conventional modem dial-up. To
counter this threat, the AT-AR256E is equipped
with a powerful Stateful Inspection Firewall that
protects against malicious attacks from the
Internet – giving peace of mind security for the
home and office LAN. In addition, a built-in
‘Intrusion Detection System’ protects against a
wide range of Denial of Service attacks.
Network Address Translation (NAT) also ‘hides’
all LAN users behind one public IP address,
protecting the LAN from external hackers.
Single PPTP or multiple IPSec and L2TP
sessions are supported using the AT-AR256E’s
sophisticated pass-through capability; standard
NAT limitations are no longer a barrier for the
power user.
