D-Link DSL-504T
Review & Specification:
The DSL-504T is an ADSL Router designed for the small office and home. This router lets you quickly and easily connect to highspeed broadband Internet and share your ADSL line. With a built-in ADSL interface, 4 10/100BASE-TX Ethernet switch ports and advanced router functions, this device gives your business and home a convenient and cost-effective way to install a secure, fast network with bottleneck-free link to the outside world.
Simplified Broadband Internet Connection
With this router, you can easily connect to your ADSL broadband line for Internet access in your office or at home. This device automatically creates an IP number and assigns for each user, simplifying everyone's logon operation.
Built-in ADSL Interface and Ethernet Switch Ports
A standard-based ADSL modem in built into this router, making connection to the Internet a breeze. The router also incorporates four 10/100Mbps Ethernet switch ports, providing ready connection for workstations and servers, while saving you the cost and trouble of installing a separate Ethernet switch.
Network Security
The router provides NAT protection for your office and home users from any Internet intruders and hackers, plus VPN pass-through for extra security. It also blocks and redirects certain ports to limit the services that outside users can access your network. Virtual server mapping is used to retask services to multiple servers. This router can be set to allow separate FTP, Web, and Multiplayer game severs to share the same Internet-visible IP address while still protecting your servers and workstations from hackers.
DMZ Host to Open Public Domain
The router supports constricted DMZ to redirect unknown packets to a dedicated server/PC behind the router, enabling a client (such as a Web server) to fully expose it to the Internet and ensure complete Internet application compatibility. 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.
