The D-Link DFL-300 Office Firewall is a hardware-based firewall designed for the small office environment. The DFL-300 Office Firewall provides an economical solution for providing small offices with dependable firewall protection against malicious attacks from hackers on the Internet. The DFL-300 provides a web-based interface for easy setup and configuration but is also designed with more advanced security features than typically found in residential gateways.
Additionally, the DFL-300 is equipped with embedded VPN support that can create multiple IPSec tunnels to remote offices. IPSec on the DFL-300 uses strong encryption with DES, 3DES, and Automated Key Management via IKE/ISAKMP. A VPN tunnel can be activated from the DFL-300 to a remote office for a secured traffic flow between the two locations for mobile users using triple DES Encryption. This offers users a way to confidentially access and transfer sensitive information. Multiple VPN tunnels may be easily created without the need to setup IKE (Internet Key Exchange) policies.The DFL-300 includes with three auto-sensing 10Base-T, 100Base-TX, RJ-45 ports. The Internal LAN port connects to the office network and the External WAN port connects to a broadband modem such as Cable or DSL. The DFL-300 Office Firewall also offers a DMZ (Demilitarized Zone) port which allows DMZ computers to be accessed from the Internet. This particular feature is useful because it alleviates congested server traffic from entering the Internal network. Web, Mail, and FTP Servers can take advantage of the DMZ port.
