### Impact

Enabling Private Google Access for IPv6 can help improve the security of your Google Cloud Platform (GCP) resources by allowing them to access Google APIs and services over IPv6 networks, rather than over the public internet. This can help reduce the risk of your traffic being intercepted or tampered with, as it is routed through Google's private network.

Additionally, Private Google Access can help improve the performance and reliability of your GCP resources by reducing network latency and eliminating the need to route traffic through third-party networks.

### How to Fix

The inspected key is \`private\_ipv6\_google\_access\`\`, and the acceptable values for this rule to pass are:

* ENABLE\_OUTBOUND\_VM\_ACCESS\_TO\_GOOGLE
* ENABLE\_BIDIRECTIONAL\_ACCESS\_TO\_GOOGLE \[source,go]

***

resource "google\_compute\_subnetwork" "pass\_bidi" { name = "log-test-subnetwork" ip\_cidr\_range = "10.2.0.0/16" stack\_type = "IPV4\_IPV6" ipv6\_access\_type = "EXTERNAL" region = "us-central1" network = google\_compute\_network.custom-test.id

## purpose="INTERNAL\_HTTPS\_LOAD\_BALANCER" if set ignored

## log\_config {

## metadata="EXCLUDE\_ALL\_METADATA"

## }

private\_ip\_google\_access = true

* private\_ipv6\_google\_access = "ENABLE\_BIDIRECTIONAL\_ACCESS\_TO\_GOOGLE" }

## 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/public-exposure/appsec-gcp-76.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.
