Use the diagram below to help yourself reference what I'm speaking about when I mention it.

Extra info:
- The "Server" computer has an openvpn server on it(windows7) that I can connect to using the openvpn client, it does not require a password or username to connect.
- The "Server" computer also will be hosting all of the files I would like to be able to access from all locations of my business.
- All computers are running windows 7
- I mainly only need filesharing.
So what I want to do is buy a DD WRT router for each of the 3 different locations that I would like networked together, and connect them to the "Server" computer's OpenVPN server.
I'm basically asking if this is possible, would I be able to file share and everything to and from the "Server" computer.
Here are some questions I have:
- What router should I buy for each building?
- Would this one work? http://www.amazon.com/DD-WRT-Router-Linksys-Wireless-N-PREINSTALLED/dp/B00BVELMG0/ref=sr_1_5?s=electronics&ie=UTF8&qid=1384887035&sr=1-5&keywords=ddwrt+router
- Will I be able to file share between computers on the network?
- Will this bring them all together?
- Am I doing this right?
