The Allied Telesis AT-AR221E is the perfect solution for the home or small office that wants to use high speed, 'always on' DSL and Cable services to access the Internet. DSL and Cable services offer speeds up to 200 times faster than 56kbps modems. Take advantage of high-speed DSL/cable connections to provide video-streaming, video-conferencing and new multimedia applications. High-base functionality and simple upgradeability make it the ideal choice for homes and businesses wanting to exploit the benefits of high-speed networking services. Build high-speed LAN backbones at home or in the office using the integral 4 port 10/100Mbps, auto-sensing, Ethernet switch. The auto MDI/MDI-X feature on all the LAN ports makes expanding the network extremely simple, by cascading additional hubs or switches to further increase the number of users. Installation takes a matter of minutes using the intuitive, browser-based interface. Simply point any standard browser at the default IP address of the AT-AR221E and get started. An easy to use Setup Wizard allows uses to quickly configure the standard features of the product. Standard Ethernet cables connect the AT-AR221E to LAN users and the Cable/xDSL modem - that's it. No configuration or reconfiguration of any PC application is required. All TCP/IP operating systems are supported including Windows 95/98/NT, UNIX and MAC. An integral DHCP server provides automatic IP address assignment to all PCs on the LAN, while both static and dynamic IP address assignment from the Internet Service Provider is supported. Some service providers use PPP over Ethernet (PPPoE) as a way of automatically assigning user IP addresses instead of DHCP. The AT-AR221E supports both DHCP and PPPoE. The AT-AR221E supports all the standard configurations of the majority of Internet Service Providers, including Dynamic IP addressing, Static IP addressing, PPPoE and PPTP. This allows the AT-AR221E to be used on almost all networks, independently of the service provider. Cable and DSL modems do not provide any firewall protection, and because they offer an 'always-on' connection, users are actually more at risk using these services than with conventional modem dial-up. However, by simply connecting the AT-AR221E between the cable or xDSL modem and the private LAN, the AT-AR221E provides a powerful Stateful Inspection Firewall that 'hides' all LAN users behind one public IP address, hence protecting LAN users from attack. It is sometimes desirable to restrict Internet access or to block specific services or applications. The AT-AR221E uses packet filtering based on destination IP address to block access to specified sites. Packet filtering can also be based on the IP port number. Different services such as e-mail, WWW and FTP use standard port numbers to communicate. By filtering all packets destined for a specified port number, the network administrator can, for example, deny all LAN users access to SMTP/POP3 Internet e-mail services, while allowing all users to access WWW/HTTP services.| Product Description | Allied Telesis AT AR221E - router | | Device Type | Router | | Form Factor | External | | Dimensions (WxDxH) | 14.1 cm x 11.2 cm x 2.6 cm | | Weight | 0.5 kg | | Data Link Protocol | Ethernet, Fast Ethernet | | Network / Transport Protocol | TCP/IP, PPTP, IPSec, PPPoE | | Remote Management Protocol | SNMP, HTTP | | Features | Firewall protection, switching, auto-sensing per device, DHCP support, NAT support, VPN support, auto-uplink (auto MDI/MDI-X), Stateful Packet Inspection (SPI), packet filtering, manageable | | System Requirements | UNIX, Microsoft Windows 95/98, Apple MacOS, Microsoft Windows NT |
