Configuration Change – IP documentation – Network requirements

Recently we found out that we had a typo in our public IP documentation – Network requirements 20.23.198.120 should be 20.23.199.120 and 20.99.133.218 should be

20.99.132.218.

How this will affect your organization:

If you made firewall IP changes in accordance with the updates in the documentation on February 5, 2023 you may have incorrect configurations.

What you need to do:

Please review your firewall configurations to ensure they match the most currently IP configurations. Replace 20.23.198.120 and 20.99.133.218 with 20.23.199.120 and 20.99.132.218 respectively.
