two gateways one static ip address

So we've got these two gateways.  Let's call them 192.168.0.10 and 192.168.0.12.

The .10 gateway has a static IP address associated with it.

The .12 gateway is much faster.

I would like to configure Windows 7 to only use the .12 gateway except for two instances, 1) the .12 connection dies or 2) we need to RDP into one of our servers at Amazon which we've configured to require the .10 static IP address.

What needs to happen?

Without using a load balancer or multihomed firewall you will not be able to automagically have Windows 7 use a different gateway based on network conditions.

If you have a firewall/router that supports Quality of Service rules you can direct RDP through one connection, HTTP/HTTPS through another, etc. However thats generally not cheap hardware.

The cheapest vendor I've used for a dual homed setup is Hotbrick, a quick google search shows they might not be around anymore but you can still buy the hardware.

I was hoping to find a software/configuration solution.

Only way to do it would be to use two different subnets and add static routes to the windows routing table.

You would have your Amazon gateway be 10.1.1.1 for example and your default faster route be 192.168.1.1.

All traffic would go through the 192.168.1.1 and you would be able to RDP to 10.1.1.1

This does nothing for your stipulation of switching routes if the default goes down but thats the best I can do via software.

I think I'll just remove the .10 from DHCP, manually configure routes for the few machines that need to get to secure locations and forget about using the .10 as a failsafe for the .12 connection.  :-(

No one's come up with an ideal, low cost solution.
