protectli FW2B specific config can only access google/nextdns & no other sites??

That shouldn't cause any of the symptoms the OP is describing, though.  At most they'd just be double NAT.

Unless the WAN network uses 192.168.1.0/24 - then all sorts of undefined behavior can happen.

@stumpy what are the IP addresses of your WAN and LAN interfaces, respectively?

Ah, valid.  I forget about those edge cases as I would never think to do that.

Based on their pastebin and comments they're using the default 192.168.1.0/24 range for LAN.

I actually left the "default" login/password so its not the login password that I would use, or are you referring to something else?

In the future you should just delete password and cert entries from configs.  That way you're covered regardless.

Thanks, will check when i get home.

As for how I check, I've been checking using the computer that is connected to the LAN port (for what its worth, the same computer I access the opnsense webgui from)

Next time check the Firewall -> Log Files -> Live View screen and see what it shows.  That will provide more information.

Also, use the Interfaces -> Diagnostics -> DNS Lookup page to test some domains and provide the results.
