I am trying to provide access to one machine on a network through the internet, so we can use Windows Remote Desktop Connection. We have a Netgear router, which prevents broadcasting of IP addresses. Anyone know how to get around this? I tried using the web interface and creating a static route, but there doesn't seem to be anyway to connect the internal IP address to the external IP address. Thx.

Not knowing your Netgear Router model I do not know the limits but if your router can accomplish what you are looking for I think you will want to look for some sort of Static NAT, or Static Mapping, or Pin-Holes. The terminology changes with gear.
If what you are doing is having Client "B", the remote PC, try to connect to client "a", your PC, there would have to be some configuration that looks like this:
Send 172.16.1.1:3389 to 10.0.0.1.

Where:
172.16.1.1 = External IP.
3389 = Windows Remote Desktop Protocol (RDP) TCP Port
10.0.0.1 = Internal IP.

If you just can't get this to work maybe you could try reversing who initiates the session. If the "hidden" IP initiates the session then a NAT "Network Address Translation" table is dynamically built on your router allowing the session to continue if Windows Remote Desktop allows this. If both clients have hidden addresses then one needs to be statically routed.

Hope it helps,
Jim

Note: Routers are great but with drawbacks which are: Blocking inbound requests and with DHCP enabled, the inability to foward ports to specific computers.

Port fowarding allows you to specifiy inbound traffic to a specific computer [which requires a static IP address scheme for LAN clients]. Port fowarding will not work with DHCP enabled on your router and to get what you want to work to work, you must configure port fowarding to foward the inbound request to a specified client.
