Question : Need to recover partition

Im not really sure where to start....
So i was installing xp and i was at the set up screen and i accidentally deleted the partion on my external drive now when i plug the drive in im prompted to formatt the drive. I downloaded a software trial and i was able to see the data on the drive.

Does anyone know about any freeware that will allow you to recover 250gb worth of data for free?

Thanks

OK...I'm stupid.  You want to create a route not a firewall rule.  Sorry....just finished a question about fw rules.  Go to Network > Routing.  Add a route and you'll see a window similar to what I've attached.  You can either select Any for the service or particular to Exchange traffic.  Select the interface for both Gateway: and Interface:
