WiFi host can’t pull an IP from DHCP

@dominikhoffmann
I was requesting a Diagnostics > Packet Capture.There is no rule to allow DHCP traffic, even it is implicitly allowed. So you won't see any packet matching a rule there.

@dominikhoffmann So you have switchports inside of pfSense which I don't have, could make thinks different.
And your switch has only one place to configure VLANs?
Same goes for the AP, maybe it can be differentiated if you want the VLANs only in the AP or also outside of the AP?

WAN net is just the network assigned by your ISP, it's not the internet.You don't show if you're vlans are tagged or untagged on your switch.
Assuming you have 3 AP's? Ports 2, 3 and 4? With 8 going to the router?if so, ports 2, 3, 4 and 8 should all be set with your LAN as pvid as untagged, and vlans 11 and 13 as tagged.
Is that what you have? -

Here is how the port tagging on the switch is presented:

That’s the way I have it set up.

Both VLANs are on the switch port associated with the physical OPT port, because that’s where the Ethernet going to my switch is plugged in.
Same goes for the AP, maybe it can be differentiated if you want the VLANs only in the AP or also outside of the AP?
If I had the VLANs only inside the AP, I couldn’t use the pfSense firewall to block access to my LAN from those two VLANs. They are supposed to provide internet access, only, and no access to other hosts or devices on my home LAN.

Here is the result of the packet capture running for about 90 s, while my iPhone was trying to get onto the newly set-up VLAN ID 13 WiFi network:
Nothing! Let me think about what that implies.
Here is a packet capture with my phone getting onto the VLAN ID 11 WiFi network (successfully):
So, evidently, devices trying to get onto VLAN ID 13 don’t get an IP address, because their DHCP request never gets to the pfSense appliance.
-
@dominikhoffmann What's running at 11.1?
this implies the request comes in (UDP port 68) and a response goes out.
-
I would run the capture on the VLAN on port UDP 68 and nothing else... just sniff the traffic. The extra stuff showing up is unhelpful.

Well, that's from the VLAN that’s working. The same packet capture running on the VLAN that is not is just crickets.

I thought of another troubleshooting step: I will temporarily re-tag my guest network with VLAN ID 13 (from VLAN 11) and will see, what happens.
-
What is the Interfaces->Switches Ports and VLAN tabs like?
You have a device with a built-in switch, you have VLANs not communicating, I don't see any screenshots of the actually Netgate's 1) Model number and 2) built-in switch programming.
Here are the pages on my 7100:

@dominikhoffmann
So something with the VLAN configuration on one of the involved devices might be wrong. You should recheck all settings. I'd suspect the switch. -
The APs routing the IoT WiFi SSID through the VLAN ID 11 interface works, while the APs routing the guest WiFi SSID through the VLAN ID 13 interface does not work.
-
@dominikhoffmann Please check out my request above for your Netgate firewall switch screen shots like what I provided...
-
That’s the answer:
I just added that last VLAN group. I knew, that I had forgotten something!
Hurray! Success!
Thanks so much, Ryan!

@dominikhoffmann You're welcome.
