***Gateway IP address subnets:** This column lists the IP address subnets of the gateway rings located in the particular region. As we retire older gateway hardware, we recommend that you open the client-side firewall to allow outbound traffic for the IP address subnets in the region you're operating.

***Gateway IP addresses (decommissioning):** This column lists the IP addresses of the gateways hosted on an older generation of hardware that is being decommissioned right now. If you're provisioning a new server, you can ignore these IP addresses. If you have an existing server, continue to retain the outbound rule for the firewall for these IP addresses as we haven't decommissioned it yet. If you drop the firewall rules for these IP addresses, you may get connectivity errors. Instead, you're expected to proactively add the new IP addresses listed in Gateway IP addresses column to the outbound firewall rule as soon as you receive the notification for decommissioning. This will ensure when your server is migrated to latest gateway hardware, there's no interruptions in connectivity to your server.

***Gateway IP addresses (decommissioned):** This column lists the IP addresses of the gateway rings, which are decommissioned and are no longer in operations. You can safely remove these IP addresses from your outbound firewall rule.
