Question : Different Gateway For Specific Program

I am wanting to set my Windows 7 PC so one particular program uses a different gateway to everything else.

Could this somehow be achieved by installing a proxy on the PC that points to a different gateway on the same subnet, and then just point this one program at the proxy?  If so what proxy software has this functionality?

The PC only has one NIC, and I am hoping for a software based solution that doesn't involve a Virtual PC.

Thanks

Answer : Different Gateway For Specific Program

If your application allows for defining proxy settings, you can set up something like this. But that ususally works only for SOCKS or HTTP proxies.

You can't bind an application to a specific IP address or (virtual) NIC,
You can't bind an application port to a specific IP address or NIC

However, you can use specific routes, if you know the target addresses, And those route can use an other gateway then "standard" addresses.
