VLAN issue with E-MSM430

[KC45069]

I have successfully created my SSIDs on this AP, and have linked them to the appropriate VLANs, one of which is our internal network. A system connecting to this SSID gets a proper IP address on the internal network, as well as the local DNS server. However, it is isolated, and can not communicate with the local DNS server, nor ping it, or anything else on the local network. How do I turn off wireless isolation on this VLAN?

Do you by chance have the 'wireless security filters' enabled for the VSC, restricting traffic to only the default gateway of the AP?
