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.

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

2. Port forwarding 3389 -> 192.168.1.2:3389 and 3390 --> 192.168.1.3:3389

To setup NAT on Ubuntu, see Ubuntu NAT. We'll add a short bit of instructions to the system to forward the ports as follows:

#Port Forwarding Stuff:
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
iptables -t nat -A PREROUTING -i eth1 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3389 -j DNAT --to-destination 192.168.1.2
iptables -t nat -A PREROUTING -i eth0 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3390 -j DNAT --to-destination 192.168.1.3:3389
iptables -t nat -A PREROUTING -i eth1 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3390 -j DNAT --to-destination 192.168.1.3:3389

NOTE: ALL OF THIS CAN BE FOUND BY TYPE "man iptables" from the command line in linux.
