Enabling a Firewall - Lumberyard User Guide

Enabling a Firewall

Open 3D Engine (O3DE), the successor to Lumberyard, is now available in Developer Preview. Download O3DE or visit the AWS Game Tech blog, O3DE Discord, or O3DE GitHub to learn more. The Lumberyard forums have been deprecated. You may view past forum discussions in the archive.

You can help protect your environment by enabling the firewall settings on all computers running the Asset Processor or Lumberyard Editor to do the following:

  • Exclude external connections to ports 4600, 9432, 9433, and 45643 from untrusted IP addresses.

  • Exclude connections from every address except 127.0.0.1.

  • If you have multiple computers that work together (e.g. a PC and a Mac), you must allow connections to ports 4600, 9432, 9433, and 45643 from the IP addresses for these computers, but exclude all other connections.

Refer to the documentation for your operating system for how to manage your firewall settings.
