configure-pat.sh for VPC NAT Instance
#!/bin/bash
# Configure the instance to run as a Port Address Translator (PAT) to provide
# Internet connectivity to private instances.
# This is pretty much the same as the configure-pat.sh script from a AWS AmazonLinux NAT instance except that we tweak
#the iptables rule to NOT NAT traffic that has to flow over the VPN but NAT anything that does'nt match our remote ends
#VPC CIDR value. This way access to remote subnet over VPN will be normally routed and not NATted to IP of our NAT instance.
#E.g. in this script, the assumption is that the VPC CIDR for the "other" end is 172.19.0.0/16. YMMV.
#See http://www.onepwr.org/2012/08/20/link-amazon-vpcs-over-a-ipsec-site-to-site-vpn/ for full atricle.
