## Impact

Using Amazon NAT Gateways (AWS NAT Gateways) for the default route can help improve the security and performance of your network. NAT Gateways allow you to route traffic from your Amazon Virtual Private Cloud (Amazon VPC) to the Internet, while also hiding the IP addresses of your instances from the Internet. This can help protect your instances from potential threats such as spoofing attacks and port scans.

## How to Fix

## \[source,go]

resource "aws\_vpc" "example" { cidr\_block = "10.0.0.0/16" }

resource "aws\_internet\_gateway" "example" { vpc\_id = aws\_vpc.example.id }

resource "aws\_route\_table" "aws\_route\_table\_ok\_1" { vpc\_id = aws\_vpc.example.id

## route { cidr\_block = "0.0.0.0/0" gateway\_id = aws\_internet\_gateway.example.id } }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/networking/appsec2-aws-35.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
