[HELP] My LAN interface have no internet access

[Patrick M. Hausen]

So no gateway entry on the LAN interface. Good, that's how it should be. So when you connect your phone to the WiFi it gets an IP address in the 172.16.10.0/24 network? And ping of 172.16.10.1 results in what exactly? What do you mean by redirect?

Can you see the phone's IP address in the leases on OPNsense?

Can you get a second PC/laptop? It would be way easier to debug this if you could do an "ipconfig /all" or equivalent on a client.

I don't see a mention of NAT or a route for the LAN network on the PPPoE (upstream) provider device. One or the other would normally be required. (I also didn't see the PPPoE-assigned IP offhand.)

That's the default and they wrote they only changed the LAN network and DHCP. 🤷�♂️

I do not click on external links and I block so called image hosting sites.

Sorry, but I have to ask : Why ?!

It's just a simple well known website in this case...

[Patrick M. Hausen]

It's a private data farming site or why would anyone provide "image hosting" for free?

If you just block all the ads and tracking and stuff the "damage" should be low in general since you don't tell them much about yourself and in general don't spend a lot of time on those website unless you are active on some kind of forum that uses them all the time...

Hello there, I'm here. I just somehow figure it out, i don't know what i just did. I just factory reset, making all again and it working(interface, dhcp). But then i have another  issue, everytime system shutdown(i simulate power down) then start up again, except WAN, all other interface will not have internet access, that really weird
I tried to change to same networks structure like Karla and got same issue
I see phone's IP address in the leases

But LAN does have Internet access?

OPNsense is not a switch. All other ports except LAN and WAN are unconfigured on a newly installed system. You need an internal switch to connect more than one device.

In case you wanted to create more isolated "LAN like" networks like a guest net, IoT, etc. - it is not sufficient to just assign interfaces, IP adresses, and configure DHCP. OPNsense comes with a global "allow all" rule on LAN, but your new interfaces don't have this. You need to explicitly create it for every additional interface.

When I first booted the system and configured it, it worked, but after a restart, it didn't.
I know OpnSense isn't a switch, so I have an internal switch.
I assigned "allow all" rules on the LAN and other interfaces, and everything worked perfectly until the restart.

Did the restart possibly revert your system to the default settings?

no, it's not revert anything.
