Hi again,

Either I can't quite figure out my tagged vs untagged ports, or there is more going on that I am missing.

I have an Edgerouter X that serves as the DHCP server for LAN and VLAN - and vlan aware is enabled -- WAN is eth0, eth1 is coms between router and switch, eth3 is a pihole. The switch is a TP Link T-2600G (jetstream line). It has 3 APs on it plus the rest of my hardwire stuff. The actual devices on the switch is the below table.

Currently system vlan has all untagged, I left it as is. I have VLAN 120 working with these port selections but I don't feel it to be correct. VLAN 140 isn't connecting to the DHCP server following VLAN120s setup - which again I believe to be incorrect. L3 interfaces show up - and the ports all show correct VLANs to use. DHCP Relay shows the correct DHCP server w/ ID 140

Based on what you can see - what should I tag the below ports as for the 2 VLANs I am trying to extend to? In the last column - I have the possible VLAN communication I would like to be allowed on the port.
