Dual WAN webserver failover/load Balance

I have been trying to find the best way to accomplish my problem but cannot come up with the optimum way of accomplishing it.

What I would like to do is load balance (75% one IP and 25% another IP) a web server and have failover in case one connection dies all the traffic is routed to the other IP.

To sum up what the scenario is, we have a Sonicwall TZ 190 with one DSL connection which has a static IP and one Wireless connection that has a dynamic IP that really does not change but it could at any time. The DSL is configured to handle 75% of the outbound traffic with the remaining going out on the wireless. The domain name to the internal webserver is currently configured 75% to the DSL and 25% to the wireless but if the DSL cuts out then someone trying to access the site will roughly have to try and access the site 4 times before it actually connects to the internal server.

I have been looking at solutions like the software Simple Failover but I don't think that will allow me to load balance 75/25 the way I would like to.

any suggestions are welcome.

Thanks,
Daniel

Re: Dual WAN webserver failover/load Balance

If this is about Public access from The Internet to your web server, then in general there should be some BGP routing in place. Another approach is probably by using some Server Load Balance appliance like F5.

For "real" load balance, you can't just rely on software unfortunately

For some organizations, such solutions may not be financially attractive. When that is the case, you might want to consider co-location. With colo, the colo provider will take care all of those (among other things) with less headache and with less money to spend. You just need to move your server over their facility and tell them what you are trying to achieve.

dalb @rogers.com	I am not familiar with BGP routing but I will look into that. Where can I find information on the Server Load Balance appliance? as for moving the appliance to another facility isn't an option because it is also the main server that runs the business management software. Also if the above are very expensive then those will most likely not be an option. Thank you very much for your input.
