Hi,

Sorry if this has already been asked but I wasn’t able to find the  
response via search.

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

F
