How to forward rdp port in debian 7 to virtual machine?

Question

Windows

There is a server with Debian 7, on which the vmware virtual machine is installed, on which Windows is installed in turn. How to forward rdp port directly to Windows? for example, the server IP is 1.2.3.4, the Windows IP under the virtual machine is 192.168.1.2. Is it necessary to forward the port so that, for example, on a third-party machine you connect to 1.2.3.4:3389 and immediately connect via RDP to Windows?

Answer 1

iptables -t nat -A PREROUTING -d 1.2.3.4 -p tcp -m tcp --dport 3389 -j DNAT --to-destination 192.168.1.2:3389
iptables -A FORWARD -p tcp -m tcp -d 192.168.1.2 --dport 3389 -j ACCEPT
