I ran into the battle of running all of my VMs and the host node under a single public IP address. Luckily, the host is just pure Debian, and ships with iptables.

What needs to be done is essentially to run all the VMs on a private internal network. Outbound internet access is done via NAT. Inbound access is via port forwarding.

Network configuration

Here’s how it’s done:

Create a virtual interface that serves as the gateway for your VMs:

import os
import subprocess
import boto.ec2
import itertools

AWS_KEY = os.getenv('AWS_ACCESS_KEY')
AWS_SECRET = os.getenv('AWS_SECRET_KEY')

# Tweak as necessary for your infrastructure
regions = ['us-east-1', 'us-west-1', 'eu-west-1']
