Chris Your first job is to establish a real baseline. That is: How fast can you really move data between the two sites without any tunnels? You may have to be creative with NATting and other tricks to get a system at each end to see the other. Once you have a proper figure to work towards then introduce OpenVPN or IPSEC or whatever. If your ~18Mbps is a real measured figure then consider: UDP vs TCP, MTU, TUN vs TAP. You don't mention what you are using already.
