My Office network consists 2 Windows servers and 25 Client PCs running windows 2000 prof. The PC's are connected through a unmanaged 100 MBPS switch and we have assigned static IP address for the computers. Right now we are using dailup internet connection which connects to a client pc running a proxy software (winproxy). The proxy software provides internet access to other client PCs. With this proxy software i can control the internet access of each individual PCs. Now we are planning to go for dataone. Which is best way to connect the dataone to a small LAN ? As far as I know, if I connect the dataone to the switch directly, it will be difficult to control the net access. If I put one more ethernet card to my gateway pc then can i use my existing proxy software to share the dataone connection ? Which is the best solution ?
