I recently began transferring files with another MAC user. We are both connected to the internet via cable modem. We have successfully established drop boxes for file transfer between one another. Unfortunately, the transfers are slow. About 12-15kb p/sec. Is there any way to speed up this process? I am connected to a router, but I have opened the required ports within the router for personal file sharing. NOTE: when in the same location, we can connect both computers to the router. The transfer speeds are almost 2 mb p/sec. But when in different locations, it slows to 12-15 kb. Any suggestions?

Thanks in advance,
