Re: Help With Load Balancing
I don't know a great deal about what you are trying to do, but I can make a few suggestions about what to ignore, and what to search for.
Your second option regarding Windows Home Server is more about spreading the load of incoming connections to more than one PC. In fact the whole concept of Load Balancing is more along those lines so using that as your search entry will probably give you misleading results.
I think the proper term for what you are talking about is WAN aggregation.
I'm fairly confident that a Cisco router could do what you want, but a solution with 5 WAN ports is likely to be very expensive.
I can't see any way that a DD-WRT capable router is going to help - at best they would have dual ports. As with the Cisco anything more than that is going to be expensive.
That really only leaves you with your first option. Other than the Cisco option this was always going to be the case because you need a single point of reference which sees all of the traffic in order to be able to direct the flow efficiently.
My idea on this would probably be a PC with sufficient ports to run all the WAN connections, plus one for the internal connection to your home PC(s). I can't envisage a low-cost solution using a Windows system, so my suggestion would be a Linux box.
