Allied Telesis Small Branch Office Router AT-AR320 AT-AR320 Manual Do Utilizador

The AT-AR320S includes an internal DES encryption
card, providing DES encryption of user data in hard-
ware—a process that is typically ten times faster than
software implementations. By carrying out the encryp-
tion in hardware there is no impact on Firewall per-
formance, so maximum throughput of user data is
maintained. DES encryption and Layer 2 Tunneling
Protocol (L2TP) allow the creation of secure VPNs
(Virtual Private Networks) across insecure cable,
xDSL, and Internet links. 3DES encryption is available
as an option for high security applications.

The AT-AR320 and AR320S are connected between
the private network (LAN) and the public network—
positioning that provides a single point where all traffic
can be logged and monitored.The AT-AR320 and
AR320S also provide event triggers, firewall event-log-
ging, and accounting information to ensure a compre-
hensive security audit trail.
