Hi, I'm using a TP link managed 8 port switch with an EAP670 access point and wish to have multiple SSIDs mapped to different VLANs. When I refer to the TP link guide (linked below), it says to make the port on the switch connecting to the router (in my case, an opnsense router) untagged. Wouldn't doing this mean that the VLAN tags are removed before reaching the router so the router won't see any VLANs? I'm thoroughly confused and assumed the port between the switch and router needed to be tagged for all the VLANs
