How to Separate Oracle Cloud VPS and ISP Internet on OpenWrt - Need Help

Hello everyone,

My router is configured to receive my Oracle Cloud VPS connection only in the "game" zone and Wi-Fi. This setup is working correctly, and the internet is being delivered via WireGuard.

However, I want to configure the LAN1 port to receive internet from my ISP. I set it up as a WAN interface, as shown in the attached image, but I’m not getting internet access through this interface.

I know that the luci-app-pbr application can handle this separation, but I’d like to know if there’s a way to achieve this through Firewall Zones instead.

Where might I be going wrong with the LAN interface configuration that prevents it from receiving internet from my ISP?

Thank you in advance for your attention and support!
