Howdy, all. I thought I knew what I was doing here, but ostensibly I do not.
Background Info
I have an ER7206 router, TL-SG3428MP POE+ switch, and two EAP670s.
Within wired network settings, I have four LANs setup, all of which have a VLAN ID set to them (1, 10, 20, 30). They are all configured identically with the exception of the Gateway/subnet, which is `192.168.VLANID.1/24` for each respective VLAN ID, and the DHCP range is set to the respective range as well. All LANs have DHCP Server enabled, and all use a manual DNS server (Cloudflare for the time being) with lease time of 120 min and default gateway set to auto. No additional settings are ticked or enabled.
Within wireless network settings, I have three WLANs set up (one for each of the non-management LANs). Just like with the LANs, the configuration is identical for each, except which VLAN is assigned, and the IOT network isn't broadcasting a 6GHz signal. Each WLAN has VLAN enabled and is set to the respective network, all of them have the default WPA Mode (WPA2-PSK/WPA3-SAE / AES), no GKUP, 802.11r, default rate limit, and no additional settings enabled.
In the configuration for the switch, I have all VLAN interfaces enabled, and all ports have the "All" profile set, which has the management network as the native, all other networks as "tagged", and the management network as untagged.
The _only_ ACLs I have are "Allow-all-to-WAN" (self-explanatory), and Allow-Personal-to-Management (allow devices on VLAN 10 to access devices on VLAN 1).
The Problem
When I connect devices to VLAN 1, 10, or 20, the devices connect, they are assigned an IP address, and I am able to use them as expected.
When I connect devices to VLAN 30, the devices are seen by the network, attempt to connect, and are _not_ assigned an IP address in the expected range (e.g., `192.168.30.4`), but are assigned a loopback address instead. VLAN 30 is expected to be set up for IOT devices; however, I just wanted to make sure the basics are working before applying more ACL rules. I have tried connecting to each network with multiple kinds of devices, and for whatever reason, VLAN 30 is the only one whose DHCP server appears to be unable to assign an IP address. Is there something I'm missing here? How can I get this set up?
If there is any additional information needed, please ask and I will do my best to provide it.
