Product Features

Network Security

Quidway® AR 18-2X Series Routers provide abundant network security features, such as

firewall, packet filtering, network address translation (NAT), authentication, authorization and

accounting (AAA), and callback. Hence, users can select different security policies to build

enterprise networks.

VPN Function

Intranet virtual private network (VPN) interconnects the geographically dispersed branches of a

company via public networks, as an extension and replacement of traditional leased line

networks and other enterprise networks. Access VPN provides secure tunnels for small-sized

users like SOHO to access the resources of company headquarters via PSTN/ISDN. Extranet

VPN extends the enterprise networks to the business partners and clients, and enables different

companies to communicate securely and privately over the public networks. Quidway® AR

18-2X Series Routers are mainly used at the access end of VPNs.

Command Line Interface

The command line interface (CLI) of Quidway® AR 18-2X Series Routers can be configured in

common ways. No special training is needed for users.

Ethernet Access

Quidway® AR 18-2X Series Routers provide 10/100MBASE-T Ethernet WAN interface. By

configuring point-to-point protocol over Ethernet (PPPoE), hosts in LAN can access the Internet

via Ethernet, and the monitoring and accounting functions can be implemented on every access

host. Therefore, Quidway® AR 18-2X Series Routers are cost-effective and widely used in the

construction of campus broadband networks.

Chassis

Electromagnetic shielded plastic chassis, which theAR 18-2x Series Routers adopt, has not only

a smooth external appearance and small size, but also can effectively shield electromagnetic

interference from various sources to make the system work more stably and reliably.
