I have installed Foldershare on several network computers (including tablet pcs) to keep a central set of data files in sync. The program uses several ports to initiate and accept connections (80, 443, 6571, and 8000). Outbound connections were fine, but inbound connections seemed to be blocked initially, so I had to set up a static ip address for one of the computers and set up port forwarding in the router for those ports to go to that ip address (FYI, I'm a newbie to port forwarding). I also set up a similar thing at home to sync up with my home data. However, I have 10 computers at the office. If I set up separate static ip addresses for each computer, how do I keep those ports open for these other addresses? Can the router forward the ports to more than one ip or a range of ip addresses? The FAQ for Foldershare doesn't seem to address this issue. If anyone can help me with this I'd be so grateful!! Most of the tablets are running XP pro, and we are running Windows 2000 server at the office.
