No internet on LAN after fresh install of OPNsense 26.1 and setup wizard

[saleh]

Hello everyone,

I have performed a fresh installation of OPNsense 26.1.
After installation, I followed the initial setup wizard and applied the configuration.
Before applying the wizard settings, LAN internet access was working.
After applying the wizard changes, LAN clients no longer have internet access.

Symptoms:
LAN clients cannot ping external IPs (e.g. 8.8.8.8, 8.8.4.4)
No internet access from LAN
Issue appears immediately after applying the setup wizard configuration

Thank you.

And what is shown in the firewall log ?

Just to update this thread: the issue is now resolved.

After further testing, internet connectivity started working normally on the LAN without any changes to the OPNsense configuration. At this point, it looks like the problem was not related to the OPNsense setup wizard.

We suspect the issue was related to our lab environment, possibly VMware Workstation networking or another temporary issue in the lab setup.

Thank you to everyone who took the time to read and assist.
