Where can I get dual wan software?

Dual Wireless Access Network (WAN) software can be used to connect and use two completely independent internet/ intranet connections at the same time running on the same machine on same operating system like Windows 2k, Windows XP Server edition or Windows 7 more recently.

This objective could be achieved through third party software, which could be installed on the system and assign particular amount of bandwidth for most-frequently used applications for each connection. However, this is most useful in case of a network of systems using the concept of 'Network Load Balancing'. The same could be done through network teaming by using two separate network cards to create a virtual network which could use the combined bandwidth of two connections.

The way to do this is through using a Dual WAN Router, wherein the two connections could be connected to a single router and then the router to the PC/ LAN. There are software packages available on purchase basis like, Hawking Technology (www.hawkingtech.com).

There are also other software available for the purpose like NAT32 Windows Software (www.nat32.com). NAT32 uses multiple Internet connections, multiple private LANs and multiple private LAN gateways. NAT32 runs on the computer with multiple internet connections available and acts as enhanced IP router for the machine and also other machines, if connected to it through LAN. The software could be downloaded from the website as a 30 days evaluation copy after which it needs to be purchased for further usage.

In addition, Windows 2k and Windows 7 has a in-built support for this purpose to use multiple adapters running separate internet connections be used on the same machine at the same time. The information is available on Microsoft Support webpage at http://support.microsoft.com/kb/258487/EN-US/. One will need to configure multiple default gateway addresses in a similar way by adjusting the metric on each default gateway address. The default gateway with the lowest metric becomes the primary default gateway. To change the metric on an adapter:

1. Open the Network and Dial-up Connections folder.
2. Right click the local area connection you want to modify, and then click Properties.
3. Click Internet Protocol, and then click Properties.
4. Click Advanced.
5. In the Adapter Metric box, type the appropriate value.
6. If you need to change the default gateway metric, click the gateway address in the Default Gatewaysbox, and then click Edit.
7. Type the appropriate metric value, and then click OK.
8. Click OK.

For a consistent stable performance. it is recommended to buy a Cisco certified hardware like Cisco RV042 Dual WAN VPN Router, which comes with a bundled software. More information on the product could be found at the following web link,
