Appendix D. Troubleshooting

Problem 1

Outbound load is only distributed over one WAN connection.

Solution

Outbound load balancing can only be distribute traffic evenly between available WAN

connections if many outbound connections are made. If there is only one user on the

LAN and only one download session is made from his/her browser, the WAN

connections cannot be fully utilized.

For a single user, download management applications are recommended. The

applications can split a file into pieces and download the pieces simultaneously.

Examples include: DownThemAll (Firefox Extension), iGetter (Mac), etc.

If the outbound traffic is going across the SpeedFusion

tunnel, (i.e., transferring a file

to a VPN peer) the bandwidth of all WAN connections will be bonded. In this case, all

bandwidth will be utilized and a file will be transferred across all available WAN

connections.

Problem 2

I am using a download manager program (e.g., Download Accelerator Plus,

DownThemAll, etc.). Why is the download speed still only that of a single link?

Solution

First, check whether all WAN connections are up. Second, ensure your download

manager application has split the file into 3 parts or more. It is also possible that all of 2

or even 3 download sessions were being distributed to the same link by chance.

Problem 3

I am using some websites to look up my public IP address, e.g., www.whatismyip.com.

When I press the browser's Refresh button, the server almost always returns the same

address. Isn’t the IP address supposed to be changing for every refresh?

Solution

The web server has enabled the Keep Alive function, which ensures that you use the

same TCP session to query the server. Try to test with a website that does not enable
