terraform-google-nat-instance's Introduction

terraform-google-nat-instance

This module provisions a NAT instance in Google Cloud that lets instances in a private subnet connect to resources outside your VPC network. A route is created to send internet traffic to the NAT instance.

Features:

VM instance
- IP forwarding enabled
- Ubuntu 20.04 LTS
- Persistent iptables
Route
- 0.0.0.0/0 destination
- 900 priority
- Route applies to instances with network tag no-ext-ip
- Next hop is NAT instance
