Cannot access the internet from the private VPC

[tayzlor]

We do this on the NAT instance -

sudo iptables -t nat -A POSTROUTING -j MASQUERADE

which is supposed to allow traffic via iptables routing from the private instances to reach the internet via the NAT machine. However this does not work at the moment so we need to fix / find a workaround

[tayzlor]

This is due to an upstream issue in terraform 0.3.7 hashicorp/terraform#1160

There is a manual workaround for now that involves clicking the NAT instance and disabling the source_dest_check

Closing - fixed in 0.4.0 which is now released
