Are you using the PC as a gateway to the internet and a router for your local network? If so can both networks connect to the internet? I am not an expert, but you will have to add a route. I am not in front of a Linux box right now but I think you need to do a route -a 10.10.10.0 10.0.0.0. This should make it work.

What you are saying is the 10.10.10.x is a direct link to your office (leased or dialup doesn't matter). How is the link to your office set up? Is it router to router or is it a dialup?
