My Windows PC is on two different networks, but I have programs that work better on a particular network. So for example, Outlook needs to use network A, but Chrome needs to use network B. I don't really want to have to add static routes every time I visit a new site, and there are some applications that still need to use the internet on network A.

What I think what I need is a program that can bind a program to a network. So that individual programs can use specific gateways... Is there such a program?

Even better, it would be great to have a local HTTP proxy which uses different gateways depending on the website I visit, but that might be out of the question...

ForceBindIP allows you to bind a program to a specific interface. You could bind it to network adapter A or network adapter B, and add it to your command line so you do not need to worry about it. I hope that helps.

Works! However it needs some improvement (you can't pass arguments to programs that you launch). – nbolton Aug 25 '10 at 9:28

Routing is handled by the O.S., not by applications; a program can only ask the system to open a network connection to a given destination address, but it's the O.S.'s duty then to route packets in order to reach it. There's nothing a specific application can do about this, unless it goes down to implementing its own TCP/IP stack.

So, is the answer: a) "I don't know of any." b) "This is impossible." or c) "This is unlikely." -- seems to me that you think it's a mixture of a and c. – nbolton Aug 24 '10 at 7:51
That's correct. – Massimo Aug 24 '10 at 9:10
In that case, I'm not entirely sure that this should be an answer. It looks more like a comment. – nbolton Aug 25 '10 at 9:29
