One of my locations currently has multiple T1's bonded. We are adding a DSL line for our customers to use while onsite, but are also wanting to use it to transfer files to a transfer site yousendit. My thinking is that I'll put a static route for yousendit's network pointing to a firewall between the customer network and my internal network. That way only traffic from my internal network to yousendit would use the DSL and all other internal traffic would go over the T1s.
Do you see any issues with this or any other way of accomplishing it?
