We have a cable internet connection with 5 static IP addresses. Initially, we had just one, which was then forwarded to our SBS internally with the appropriate ports opened up for RWW, etc. We added the other statics to be able to access 4 other machines on the internal network directly through RDP. The main reason is that the iPhone doesn't support ActiveX, so RWW is out of the question.
Since port forwarding seems to only account for one external IP address, how can I map an external IP address to an internal IP address so that each static external will access an internal machine? The router being used is a NetGear WNR3500, and while the router isn't handling DHCP (SBS is), we have address reservations, so they are basically static internals.
Any assistance will be greatly appreciated!
