Hi all, I need help understanding switching and how to get VLAN IDs passed through to my router successfully. Current State - I have a wired router (Mikrotik hEX) that has a wireless access point connected to it. That access point has 5 SSIDs, each assigned their own VLAN ID. On the router, I have each ID mapped to a VLAN "interface" under the physical port. I then have each of the interfaces set up with their own address pool/network/DHCP server. This currently works well, and depending on which VLAN someone connects to, they are put onto the correct "network", and i have cross network communications blocked. I recently picked up a Netgear Prosafe GS728TP for $50, and i wanted to connect the access point to it, and have it pass those VLAN IDs through from the access point to the router. I am lost as to where to go from there. It would appear that I would need to set up the VLANs on the switch (matching what I have on the access point and router), which I have done. I played with assigning membership (tagging and untagging) the port where the access point was plugged in to each of the VLANs, without any luck. I plugged the switch in the same port i had been plugging in the access point, so it should not be an issue with where the router is expecting the VLANs to be coming from. So how does switching work with VLANs? if i tag a port, does it assign all traffic coming in on that port that VLAN ID? Does tagging just mean that if a device inserts the VLAN in the message header, that the switch can read that header and pass it along? Is the fact that vlan 1 is set as untagged for all the ports causing an issue (seems it has something to do with that being the management vlan)?
