The managed switch is setup with the SFP+ port using VLAN tagging for the 4 noted VLANs, and individual ports are setup as access ports for the different VLANs. What's interesting is that I can see that this communication is working properly when vlan-filtering is disabled and I'm plugged into an access port, Winbox shows the IP address of the interface for just that VLAN. It also shows an interface with an IP address of 0.0.0.0 which is puzzling. In this state I can use the Winbox via MAC address to contact the router, but I can't get an IP from the DHCP server, and I can't contact the IP address even when I assign a fixed IP to the workstation in that subnet. As soon as I activate vlan-filtering the router becomes completely unreachable over this interface.
Here's what I've put together based on the documentation and various examples in the forums:

I'm clearly missing something basic here - anyone have an idea?
