# Day 30 : Enable Internet Access for Private EC2 using NAT Instance

Welcome to Day 30. In this lab, you will learn how to enable internet access for a private EC2 instance using a NAT instance. You only need to set up an EC2 instance as a NAT instance.

### What is a NAT Instance?

A **NAT Instance** allows **private subnet instances** to access the **internet (outbound only)** while blocking inbound internet traffic.

> ⚠️ AWS recommends **NAT Gateway** for most cases, but NAT Instance is still valid for:

* Custom firewall rules
    
* Cost optimization (very low traffic)
    
* Legacy architectures
