We have a T1esque connection with 64 addresses assigned from a router we do not control. On this connection we have 5 heavy use emplyees and 300+ websites being hosted - and are starting to fill up the connection.
Given that a large portion of the bandwidth is being eaten by the employees, I decided that an inexpensive way to minimize bandwidth would be to get a standard office connection (Cable, DSL, etc.) and offload the employee usage onto a dynamic connection.
Then I started thinking - after reading the Acceptable use Policies of my local provider - that the second heaviest users were exclusively FTP users, and they might legitimately benefit from the unused bandwith from the "dynamic" connection. And THEN I thought, what if I used some sort of DNS round-robin to check the "current-IP" of an interface and load balance from the dynamic addresses to the static one...
Does anyone see where I am going and have any suggestions for getting there? Are there any ready made solution for doing something like this?
I have a hotbrick, which allows a dual-WAN configuration - but that is really for outgoing, not incoming... does anyone know of an "incoming" solution?
