D-LINK DI-LB604 EXPRESS ETHERNETWORK 4-PORT LOAD BALANCING BROADBAND ROUTER, introduces a 4-port router designed for the small business. The DI-LB604 Load Balancing Router embodies the heart of a small business – low overhead and high return on investment. Featuring dual WAN ports and four LAN ports, this router provides consistent network uptime and reliable Ethernet connectivity.

One of the main differentiators the DI-LB604 has from most routers is its dual WAN ports. With the ability to connect up to two Internet connections, the total available bandwidth doubles in capacity and therefore provides a tremendous increase in network efficiency and user productivity. Dual WAN ports also provide a fast-acting failover response mechanism; if one Internet connection goes down, the other automatically takes control to ensure continuous network uptime.
The built-in four-port switch provides computers on the LAN with network connectivity and Internet access. Connect up to four PCs or other networking devices to access company resources and use the Internet. The DI-LB604 is a scalable solution that allows users to add switches as business grows and network needs expand.

The DI-LB604 also features the dual Stateful Packet Inspection (SPI) and Network Address Translation (NAT) firewall with Denial of Service (DoS) attack protection to safeguard your network. This helps keep your network reliable and secure while maximizing the productivity of your network clients. E-mail alerts and a Syslog support ensure that network administrators have the information they need to maintain the network infrastructure. Combine these features with full System Logging, Static DHCP, Access Control List, VPN pass-through, and Network Diagnostic Tools ensures your network is fully protected from malicious attacks and outside intruders.

Setup for the DI-LB604 is straightforward. All the DI-LB604’s settings and configuration can be managed via a web-based utility. Firmware upgrades and automatic notifications are also readily available to ensure the router is always up-to-date.

With businesses becoming increasingly network-dependent, the need to invest in a reliable network solution is crucial. With load balancing capabilities and advanced firewall protection, the D-Link DI-LB604 offers high return on investment for any small business.

FAQ on the Product :
Does this unit combines the total bandwidth speed?

No, it just split up the bandwidth speed. Let say I’m downloading on FTP site while I’m also using HTTP browser. Setting it up the protocol that all FTP transactions will be at ISP 1 (WAN1) and ISP 2 (WAN2) for the HTTP protocol. Another term for combining two or more SAME internet connection would be BONDING.

Does this doubles the total bandwidth capacity?

It depends on terminology, Yes if you set it up like I mention earlier.

For example, a good analogy would be in this scenario, you got 10 PCs connected on the switch/hub to router DI-LB604, you got ISP1 connected to WAN1 and ISP2 connected to WAN2. Carefully assigned static DHCP on the 10 PCs (split up the 10 PCS to 5/5 ratio).

WAN1 (ISP1) would be 5 PCs with up to .44 range while,
WAN2 (ISP2) would be 5 PCs with up to .49 range.

Route the IP ranges carefully on the designated ISP.
