Tanımlama:

Simplified, Cost-saving Broadband Internet Connection
The DI-764 is designed for the office and public sites like hotels, airport lounges and convention halls. It allows easy sharing of broadband Internet through a DSL or cable modem from anywhere without the need for wiring. At the public sites, paying customers wishing to access the Internet can be easily added to your network. To let everybody logon, this device automatically creates and assigns an IP number for each user, simplifying every one's logon operation.

Ready Connection
With built-in wireless LAN and 10/100Mbps switch, the DI-764 provides ready connection for mobile users, workstations and servers, with or without the network wires. The built-in functions save you the cost and trouble of installing a separate wireless LAN and Ethernet switch.

Dual-band Wireless Access
The DI-764 gives wireless users access to the Internet and your network servers no matter if their laptops or PDAs are equipped with 802.11a or 802.11b wireless interfaces. Furthermore, wireless users operating on different 5GHz and 2.4GHz frequency bands can also communicate with each other as if they were using the same network type. The DI-764 gives 802.11a users network speeds of up to 54Mbps and 802.11b users 22Mbps enhanced speed. Users with 11Mbps 802.11b equipment can also operate with the DI-764 transparently.

Network Security
The DI-764 provides NAT protection for your office and home users from Internet intruders and hacker attacks, plus VPN pass-through for extra security. It blocks and re-directs certain ports to limit the services that outside users can access your network. Virtual Server Mapping is used to re-task services to multiple servers. The DI-764 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. Protection for 802.11b wireless users is provided through a 256-bit strong WEP data encryption scheme. For 802.11a, it's 152-bit WEP encryption.

Policy-based Content Filters
Easy-to-apply content filters can be set based on MAC address, IP address, URL and/or domain name and scheduled to be in effect at certain hours of the day.

DMZ Host to Open Public Domain
You can configure any of the built-in LAN ports to function as a DMZ port. A DMZ setting can be applied to a single client (such as a Web server) behind the router 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 business from your office while maintaining protection for the rest of your office LAN.

UPnP Enabled for Compatibility
The DI-764 is designed for easy and robust connectivity among heterogeneous standards-based network devices. Computers can communicate directly with the DI-764 for automatic opening and closing of UDP/TCP ports to take full advantage of security provided without sacrificing functionality of on-line applications.

Network Time Protocol (NTP) Support
The DI-764 supports the Network Time Protocol (NTP), allowing you to install a time server behind the router to symchronize time for your network environment. This protects you from the risks inherent in obtaining Internet, minimizes security risks from the outside, and maximizes time accuracy on your network.
