How to organize remote access to the server via RDP through a cisco router?

Question

Cisco

Comrades, help is needed.
There is a router cisco 2921, behind it there is a server. The server needs access "outside" via RDP.
There are also cameras behind the router, from which forwarding "out" via rtsp has already been done and is working.
Actually, it was undertaken, by analogy with the camera, to make forwarding for the server, but already on port 3389.
The result is this config:

no ip ftp passive
ip nat inside source list NAT interface GigabitEthernet0/1 overload
ip nat inside source static tcp 10.4.208.2 3389 192.168.1.2 3389 extendable \\ line added to config for server
ip nat inside source static tcp 10.4.208.130 554 192.168. 1.2 16000 extendable \\ camera forwarding
ip nat inside source static tcp 10.4.208.131 554 192.168.1.2 16002 extendable \\ camera forwarding
ip nat inside source static tcp 10.4.208.132 554 192.168.1.2 16004 extendable \\

However, it still fails to connect to the server. The server has Windows Server 2012 installed, access to the server within the network via RDP is available. But from the outside it is not possible to connect to it.
What could be the problem?

Answer 1

The port may not be open in the ACL on the outside interface.
show run | include 16000 - returns how many rows? If more than one, look for this ACL in the config and add 3389 to it, also by analogy with 16000.

Answer 2

1. Construct a cone. (Axial + generatrix of the side surface + generatrix of the base)
2. On the sketch perpendicular to the plane of the base, draw a sketch in the form of a parallelepiped rotated to the desired angle. The degree of ellipticity of the section will be adjusted by the angle of inclination accordingly.
Naturally, there are a bunch of other methods, for example, through building a section plane at an angle to one of the planes in NC, and build a sketch for a cutout already on it. Then the angle can be tied to a variable, for example, not to rebuild the sketch, but to change the value of the angle.
