Cable/DSL VPN Router With IPSec and 4-port Switch
DI-804V
Cable/DSL VPN Router
Features
The DI-804V is a high-performance broadband Internet Gateway Router with secure data transmission designed for branch office communication.
Cost-effectively linking a small office to the outside world through the Internet, the DI-804V offers an alternative to the cost-prohibitive point-to-
point dedicated connectivity of leased lines. This business-class router provides IPSec security for Virtual Private Network applications, enabling
you to extend your branch network to remote networks, such as your corporate office or a trusted supplier, to act as if the two are a single LAN. In
addition, the DI-804V also provides cost-saving Internet functions to let you share a single cable/DSL modem and ISP account among your office
users, while providing them with physical connections through the built-in LAN switch ports.
Secure Transmission Over the Internet
IPSec and Multi-Level VPN Services
Powerful Routing Engine
Business-class LAN Security
The DI-804V prevents your confidential data from being accessed and
tampered with when traveling along the public Internet to your
destinations. Through VPN tunneling protocols, the DI-804V privatizes
your communication channels. You can safely exchange mail and data
with your head office over the Internet, without fear of observation,
modification, or spoofing.
With support for up to 8 IPSec tunnels, the DI-804V can provide
flexible VPN implementation for data confidentiality, integrity and
origin authentication to remote sites. Supported data encapsulation,
encryption and authentication options include IP ESP, DES, 3DES, MD5
and SHA-1. This enables you to carry out applications such as virtual
private networks, including Intranets, Extranets, and remote user access.
The DI-804V is equipped with a powerful 32-bit RISC CPU and large
RAM to perform its intensive security tasks. This allows the router to
run without data throughput degradation while supporting DES/3DES
encryption and other security features.
The DI-804V provides firewall security using Stateful Packet Inspection
(SPI) and hacker attack logging for Denial of Service (DoS) attack
protection, plus VPN pass-through for extra security. SPI inspects the
contents of all incoming packet headers before deciding what packets
are allowed to pass through. The DI-804V also blocks and re-directs
certain ports to limit the services that outside users can access on your
network. Virtual Server Mapping is used to re-task services to multiple
servers. The DI-804V can be set to allow separate FTP, Web, and
Multiplayer game servers to share the same Internet-visible IP address
while still protecting your servers and workstations from hackers. To
monitor hacker attacks, the DI-804V can log up to 32 event messages
showing possible attacks.
A DMZ setting can be applied to a single client (such as a Web server)
behind the DI-804V to fully expose it to the Internet and ensure
complete Internet application compatibility even if the specific port is
not known. This allows you to set up web sites and e-commerce
applications from your office while maintaining protection for the rest
of your office LAN.
Of course, the basic benefit is to share the broadband line to the entire
office, using a single cable or DSL modem. To let everybody logon,
the DI-804V automatically creates and assigns an IP number for each
computer, simplifying every one's logon operation.
With 4 built-in auto-sensing 10/100Mbps Fast Ethernet switch ports,
the DI-804V provides ready connection for workstations and servers,
saving you the cost and trouble of installing a separate LAN switch.
The DI-804V is designed for easy and robust connectivity among
heterogeneous standards-based network devices. Computers can
communicate directly with the DI-804V for automatic opening and
closing of UDP/TCP ports to take full advantage of security provided
without sacrificing functionality of on-line applications such as video
conferencing.
