WAC510 as router connected to GS308E VLANs

FYI: I have a BR200 router which allowed me to try WAC5xx in AP mode and VLAN with GC110 as my switch which allowed setting trunk mode on the AP port and the router port.  I wanted to say that the BR200 did not have much flexibility in passing out DNS address with DHCP, it would only give its own address (acting as DNS relay or proxy or whatever appropriate name is).  Although I could live with that concept, I seemed to find that it added around 72ms to DNS transactions - perhaps that is the type of non-security "bug" which isn't being addressed.  I found that out after my dealer return period, but it bugged me enough to abandon BR200 and I've been happy with a non-Netgear router that I purchased instead.  That other router would let me give out alternative DNS address in DHCP if I wanted, but I go ahead and let it default to its own address (for the relay or proxy or whatever you call it) but there is no longer extra 72ms delay.

Note: I did not personally confirm the statements about WAC510 in router mode only allowing one specified VLAN.  I thought the UI allowed setting multiple SSIDs each with separate VLAN, so like you said I would expect the LAN port be sending out packets with tagged VLANs, and then you'd hook that to a switch which has trunk mode set for the WAC510 port.  I get confused with some other details mentioned such as PVID, lots of times there is teminology which relates to the style of VLAN which is based on which physical switch port you are connected to (and adding a tag).  I think on a MX510TX switch which didn't list "trunk" mode I added the VLAN numbers in the switch and then somewhere in the port setup I listed those as VLANs which were allowed through the port.  No adding tags - just being sure that I had those multiple VLANs specified as allowed through (otherwise the packets disappear inside the switch).
