Howdy and thanks for contributing to our repo. The Cloudflare team reviews new, external PRs within two (2) weeks. If it's been two weeks or longer without any movement, please tag the PR Assignees in a comment.

We review internal PRs within 1 week. If it's something urgent or has been sitting without a comment, start a thread in the Developer Docs space internally.

PR Change Summary

Clarified the usage of connectivity.cloudflareclient.com in the WARP tunnel documentation.

  • Specified the IPs used for connectivity verification inside the WARP tunnel.
  • Emphasized that connectivity.cloudflareclient.com should not be used in firewall policies.
  • Reiterated that IPs do not need to be added to the firewall allowlist.

How can I customize these reviews?

Check out the Hyperlint AI Reviewer docs for more information on how to customize the review.

If you just want to ignore it on this PR, you can add the hyperlint-ignore label to the PR. Future changes won't trigger a Hyperlint review.

Note specifically for link checks, we only check the first 30 links in a file and we cache the results for several hours (for instance, if you just added a page, you might experience this). Our recommendation is to add hyperlint-ignore to the PR to ignore the link check for this PR.

- `162.159.197.4`
- `2606:4700:102::4`

Because this check happens inside of the tunnel, you do not need to add these IPs and domains to your firewall allowlist. However, since the requests go through Gateway, ensure that they are not blocked by a Gateway HTTP or Network policy.

`connectivity.cloudflareclient.com` is used internally by WARP and should not be used in firewall policies.

@samin-cf maybe something like this to acknowledge that it could be visible to customers, I feel like this particualr hostname has been brought up a lot in troubleshooting.
