AR750 Series

Secure VPN Routers


Secure Modular Routing Solution

The AR750S has been designed with the needs of small-to-medium enterprises and branch offices in mind.  The AR750S offers significant advances in processing performance, Quality of Service (QoS), routing, remote connectivity and security.

With dual hot-swappable AC or -48V DC redundant Power Supply Units (PSUs), the
AR750S-DP meets the needs of Telco customers.

Extensive VPN Cabability

The AR750 Series provides extensive IPSec-based VPN capability, allowing the interconnection of offices, remote teleworkers, and all users requiring secure access to a corporate network. The AR750 comes complete with integrated hardware acceleration, which maximizes encryption throughput and removes the need to purchase a hardware upgrade package.The AR750 is compatible with industry standard IPSec VPN clients.


In addition to hardware-based encryption, the AR750 Series offers advanced security features.Traffic filtering uses the source and destination address, port, protocol and TCP packet type to provide ultimate traffic control. A Stateful Inspection firewall provides an increased level of security and complements packet filtering. HTTP and SMTP proxies provide improved control over web and mail communications.


Dynamically identify high-priority voice, video and application traffic, to maintain appropriate service levels. Advanced QoS allows voice, video, and data traffic to apply QoS within individual IPSec tunnels as well as IPv6 to IPv4 tunnels.


The AR750S-DP has dual hot-swappable AC or -48V DC redundant PSUs packaged in the 1RU rack mount chassis, providing the ultimate in space saving, reliability and resiliency. The AR750-DP can operate on just one PSU if required. These features, combined with front-to-back cooling, make the AR750S-DP perfect for high-density rack environments where space is at a premium.


Designed to meet the needs of today's networks, the AR750 Series provides superior performance. While most secure routers have Stateful Firewalls with NAT, QoS, and IPsec VPN termination capability, very few can perform all three functions and still provide excellent performance with the mixed packed sizes seen in real networks. 

Stateful Firewall inspection, NAT and QoS: >50Mbps @ 64 byte packets

Stateful Firewall inspection, NAT, QoS, IPsec VPN (with AES 256 bit encryption):
>35Mbps @ 72 byte packets

The AR750 Series can achieve up to 195Mbps IPsec throughput with bidirectional traffic. This level of performance enables secure site-to-site VPNs over multiple WAN interfaces, while still firewalling the local network across multiple LAN ports.

Comphrehensive Management and Configuration

The AR750 Series comes with a comprehensive suite of management features and is also compatible with SNMP-based management packages. Allied Telesis SNMP support extends to SNMPv3 to provide secure management. An extensive command set is available via the Command Line Interface (CLI), and a browser-based Graphical User Interface (GUI) is also provided to simplify the configuration and management of the routers. The GUI provides access to default setups in key management areas, and provides access to regional settings.

WAN Load Balancing

The AR750 WAN Load Balancer combines bandwidth from multiple WAN connections for increased throughput, redundancy, and reliable WAN connectivity. When a router simultaneously connects to multiple WAN networks, the WAN load balancer will distribute the traffic based on one of a number of selectable algorithms.
