Can't traverse to Internet

[baqwas]

Hello!

Need help, please. What are the recommended steps to troubleshoot LAN desktop access to the Internet?

The Lobby Dashboard shows the WAN Gateway as online.
The Firewall LAN rules, per default, allow LAN to any.
The Firewall WAN rules have no outbound block.
dig _gateway from desktop client responds correctly with the Open sense IP address.
The desktop client has a DHCP lease with correct gateway assignment.
Dig www.google.com or any Internet IP address fails with communication error (timed out) 127.0.0.53#53
ISP installed new modem and this error started.
Pihole logs show that Google Home Mini Speaker is calling "home"
Pihole is syncing with NTP Pool servers.

Where have I messed up?

Thanks.

OPNsense 24.1.8-amd64 on ProtectLi fw4b
Desktop client is Ubuntu 24.04

Please "close" the issue.

The ISP had configured the modem incorrectly! The 3rd person finally listened exactly what I needed and the connection was established.

Sorry for posting in haste yet again.

Regards.
