Setting up an RDC connection to a local VM

[User26401 1]

Hi All,

 

I'm trying to set up RDC so I can connect to my local machine (actually a VM on a host server) from the internet. Would this be the general method:

 

1) Forward a port (say 4567) on the AirVPN settings to local port (say 4567) and enter a ddns name (say my-super-vm)

2) On my router (Asus RT-N66U Tomato, 192.168.1.1) Forward from VPN (not WAN) port 4567 to Local VM Machine (say 192.168.1.51) - I use Bridged Networking, so am assuming router is 'aware' of VM on host 192.168.1.2?

2a) Or, do I forward from VPN to Host 192.168.1.2, then set a firewall rule on Host to forward port 4567 traffic to VM?

3) Open RDC port on VM.

4) From a MSTSC client on another internet facing computer, connect to my-super-vm.airvpn.org:4567

 

 

Is the above OK or am I barking up the wrong tree? Any help or pointers appreciated, especially around router stuff as I assume I'll need iptables commands?
