VX-18-2X Series routers are oriented to Small Office Home Office (SOHO) users. They include VX-18-20/18-20S/18-21A/18-21B/18-22-24 models. Currently, VX-18-2X Ethernet routers consist of two types in terms of LAN interface density:
- VX-18-20/18-20S/18-21A/18-21B (four LAN interfaces by default)
- VX-18-22-24 (24 switched LAN interfaces), in which VX-18-22-24 has the densest LAN interfaces.

VX-18-2X Series routers are Ethernet access routers, and provide 10BASE-T or
10/100BASE-TX interface in the uplink direction and 10/100BASE-T Ethernet interface in the downlink direction. The interfaces provide Layer 2 data exchange and can implement port isolation. In addition, the built-in hardware encryption chip of the AR 18-20S greatly enhances the encryption performance.

Product Features:
	Network Security:
	VX-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. VX-18-2X Series routers are mainly used at the access end of VPNs.
	Command Line Interface:
	The command line interface (CLI) of VX-18-2X Series Routers can be configured in common ways. No special training is needed for users.
	Ethernet Access:
	VX-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, VX-18-2X Series Routers are cost-effective and widely used in the construction of campus broadband networks.
	Chassis:
	Electromagnetic shielded plastic chassis, which the AR-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. Back to Top
