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.
