Question on HWMP+ and VLANs

I tend to over think and confuse myself and I think I have been successful in doing this again. I have been playing with HWMP+ and have several 9 to 10 radio mesh network running fine. What I am trying to figure out is I have a customer that requires a dual mesh setup. One secured for a sales application and another for a guest network; it seemed simple enough.
My plan was to use several RB/433AH boards, each with dual radio cards. One card for the staff network the other for the guest network. I created two HWMP+ mesh networks one called staff and the other guest- so far so good. When I went to add the ports for the two mesh networks is where I ran into trouble. Since I cannot have the same Ethernet port in both mesh networks, and I really don’t want to run multiple Ethernet cables to the radio, I thought I would just add two VLANs to the Ethernet and attach the each VLAN to its respective mesh. This is where the confusion comes into play.
I have several 433’s configured in this same manner terminating into an RB/1100AH. So I have 433AH-A with Ether1 setup as a trunk port and 433AH-B Ether1 setup as a trunk port.
433AH-A terminates to Ether2 on the 1100AH, which is also setup as a trunk port with each VLAN attached to its proper mesh.
433AH-B terminates to Ether3 on the 1100AH, which is also setup as a trunk port with each VLAN attached to its proper mesh.
Each mesh on the 1100AH is setup as the portal. My problem is that I cannot ping from one radio to the other and cannot get to the internet. If I remove the VLANs and run as a single mesh everything runs fine. If anyone has any input it would be greatly appreciated. My thought at this point is that you cannot do VLANs a crossed an HWMP+ mesh; is this true? Has anyone accomplished something similar in the past that can shed some insight or is there another way to separate the two mesh networks?

Did you ever get this to work?

One suggestion would be to use the EOIP instead of VLANs as they will have different MAC address.
Then you can add each EOIP interface to specific mesh group.
