Cannot get Remote Desktop to work on C7000-100NAS
OK, so I have switched from the Motorola SURFboard 6850 to the C7000. I cannot get Remote Desktop to work from my Android or WP device.
The remote PC is listening on port 3389. I've had to manually open ports 80, 443, and 32400, and have verified that they were opened. I have to be missing a step somewhere.

How about opening port 3389?
Yes, 3389 is open.
I am going to update my original post because I failed to look at the clock (had to be somewhere else), and omitted some things.
OK this is weird: I cannot seem to figure out how to edit my first post. :(
So, I have a domain with 1&1 (domain.net, for example). I go to 1&1 and do a HTTP redirect to the IP address of my modem.
On my previous modem, a Motorola SURFboard 6850, opening ports was pretty straight-forward, though I don't have it hooked-up anymore, there was an extensive list of options to chose from (unlike the seriously anemic list in the C7000).
One of the machines I am trying to connect to is at xxx.xxx.x.99 (for example). In the Port Forwarding page on the previous modem, I put that info into "Local IP"; "Local Start Port" and "Local End Port" would be 3389; "External IP" would be 0.0.0.0; "External Start Port" and "External End Port" would be 3389; "Protocol" is TCP.
On the machine itself, we had to do a bit of editing in the Registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp]
"PortNumber"=dword:00000d3d
Also on the machine, IP4/IP6 were enabled in the NIC adapters.
Finally, using MS Remote Desktop for either my WP or Android device, I would connect using domain.net:3389.
This setup worked and I had connections to two machines on my network, with my only having to repeat the steps for every new machine (and also changing the port number). But for some reason, I cannot get squat to work with the C7000.
I did find a tutorial, but it talked about needing to make a Static IP for my device (assuming the remote PC I wanted to connect to, which if true, would just add even more work since I have several machines I need to remote into).
Hope this helps...
You can use DHCP address reservations (under LAN setup) instead of static IP addresses. The idea is to keep the IP addresses that are assigned to your server stable. Otherwise, the port forwarding rules will stop working if the addresses change.
Other than that, the tutorial looks reasonable. Set external starting and ending port to 3389. You can select Use the same port range for Internal port or else manually enter 3389 for internal starting and ending port. Set External IP to Any. Make sure to click Apply to save the rule. Try rebooting the router. Sometimes, the rule won't take effect until a reboot.
Does the C7000 have a public IP address? Note, if the Internet port's IP address starts with 100.x.x.x, then it's not a public IP address. Your ISP is doing NAT and port forwarding will not work.
You should not have to change the Windows Registry. 3389 should be the default port used by RDP.
Thanks, Ether...
Dunno why, but Netgear seems to be making this more difficult than it should, so I might need some walkthrough on this. I've been playing with different things all dang day and nothing seems to be working. One of the issues I am going to have is that I have like 5 PCs I need to remote into and this doggone router is making things difficult.
The problem is that the device is requiring me to open ports and then assign them to a specfic IP of a local machine...and I cannot do that twice. Example PC1 and PC2 cannot share port 80 or 3389 or anything, unless I am missing something.
I did assign address reservation under LAN Setup, otherwise that's all I have.
Yes, I have the Public IP of the modem, so no problems there.
