How to tell ruby net libraries to use a particular network interface?

Question

Hi,

I'm doing some page scraping for a client and need to connect to their vpn server. So I have the vpn client running on my linux box, and this creates a new interface, say ppp0. Now, when I run Mechanize/open-uri, etc. I need to be able to bind specifically to this particular interface, because the other interfaces are to the internet in general. How do I do this?

Thanks

If what you are connecting to over the VPN isn't also available over the open internet you shouldn't have to do anything and the internal TCP/IP networking stack should sort out the correct interface automatically.
