Section 3: Load Balance
Configuring Load Balancing
The Twin WAN line of products uses a session based Load Balancing algorithm by allowing you to manage sessions using several different options:
 |
By monitoring real time speed of both WAN connections, the Twin WAN Gateway will establish new sessions on the WAN port with the lower speed. Use this if there is a fairly even speed on both lines and would like to benefit the most from the speed available.
|
|
Same as above but in this case, the Twin WAN Gateway monitors the packet flow and tries to maintain an even number of packets. Use this if transmitting a lot of small packets, such as web browsing and Usenet. This helps you maintain the best latency.
|
|
The Twin WAN Gateway tries to maintain an even number of sessions on each WAN port by looking at the current amount of sessions currently established. This is a very general setting only to be used if you have similar types of connections (Cable and Cable, DSL and DSL) to promote good Internet traffic.
|
|
Load Balancing traffic by IP Addresses is the recommended method for doing specific online tasks that require the same IP Address to be loosely binded to a specific WAN port. Select this method when using real time software applications that require traffic to be sent and recieved from the same IP source. (ex. secure online banking, day trading software, etc.)

Enable – Use this to enable your Load Balance settings.
Balance Type – Select the desired Balance Type:
- Bytes rx+tx – Traffic is measured by Bytes.
- Packets rx+tx – Traffic is measured by Packets.
- Sessions established – Traffic is measured by Sessions.
- IP Addresses – Traffic is measured by IP
Addresses
Loading Share on WAN 1 –
Enter the percentage (%) of traffic to be sent over WAN 1. The WAN port with the greater bandwidth should be given a higher percentage of traffic over the other WAN port.

This section displays the current traffic data of WAN 1 and WAN 2. You can use this information to help you “fine-tune” the settings above.
This section displays cumulative statistics. Use the Restart Counters button to restart these counters when required.
