AT-AR450S

Enterprise Class Security Router

The AT-AR450S is an enterprise-class security

router offering versatility, integration,

performance and security for medium-sized

business and enterprise networks.

The AT-AR450S is a versatile one-rack unit

(1RU) security router designed to provide up

to Seven 10/100 Fast Ethernet interfaces and 2

asynchronous (RS-232) ports, making it a first

class choice for Enterprise Solutions.

One 10/100Mbps WAN (Eth 0) Ethernet Port

is offered for a broadband connection to the

WAN network and a 10/100Mbps Ethernet

De-Militarised Zone (DMZ) (Eth1) Port

provides a second local network publicly

accessible from the Internet by authorised

users. The AT-AR450S Security Router also

comes with five Layer-2 switched LAN ports

and two dial-up asynchronous ports.

The 2 asynchronous (RS-232) ports provide

115kbps dial-up for external modems to either

backup the dedicated link or provide top-up

bandwidth for the network link. Full modem

control is supported and both asynchronous

ports can be multi-linked with PPP for extra

bandwidth.

Security

Allied Telesyn’s high performance Stateful

Inspection Firewall common to all routers and

Layer 3 switches provides different levels of

security to increase the overall security of

business critical information.The AT-AR450S

delivers up to 100Mbps of firewall throughput

with the ability to handle over 18,000

simultaneous sessions. With on board

hardware encryption the AT-AR450S offers

DES, 3DES and AES (Advanced Encryption

Standard) hardware encryption using up to

256 bit key code. The AT-AR450S has

integrated hardware VPN acceleration

delivering up to 65Mbps of 3DES VPN + NAT

and Firewall throughput and up to 40Mbps of

AES-256 VPN + NAT and Firewall throughput.

AES-Encrypted VPN

The AT-AR450S supports the advanced

Encryption Standard (AES). AES is a Federal

Information Processing Standard (FIPS 197)

that specifies a cryptographic algorithm for use

by U.S. Government organizations to protect

sensitive, unclassified information.This is the

most advanced encryption to open a secure

VPN channel.

VPN IPsec

IPsec (Internet Protocol Security) is a set of

protocols for security at the network or packet

processing layer. Early approaches to security

were performed at the application layer of the

communications model. IPsec is critical for

secure virtual private networks and for remote

user access through dial-up connection to

private networks. A key advantage of IPsec over

earlier implementations is that security

(encryption and authentication) can be easily

applied without requiring changes to individual

user computers.

There are two choices of security services with

IPsec: Authentication Header (AH) and

Encapsulating Security Payload (ESP).

AH provides authentication of the sender of

data and ESP supports both authentication of

the sender and encryption of data as well.The

specific service information is inserted into the

IP packet payload as a header. Separate key

protocols can be selected, such as the ISAKMP

protocol.
