In order for you to do port forwarding for your server, you must setup the iptable rules. I'll give you a separate video for that. In order for you to do port forwarding for your server, you must setup the iptable rules. We need to pieces of functionality:

 1. NAT
 1. Port forwarding 3389 -> 192.168.1.2:3389 and 3390 --> 192.168.1.3:3389

To setup NAT on Ubuntu, see [[https://help.ubuntu.com/community/Internet/ConnectionSharing#Ubuntu_Internet_Gateway_Method_.28iptables.29|Ubuntu NAT]]. We'll add a short bit of instructions to the system to forward the ports as follows:

iptables -t nat -A PREROUTING -i eth0 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3389 -j DNAT --to-destination 192.168.1.2

Virtual Network Configuration

Below is a diagram that shows how your virtual network sees the world and how the world sees it. We have eliminated for the moment the complications of the <<latex($\mu$)>>Cloud. The IP address 216.249.119.123 is a place holder for your IP address.
