Basically you need to turn port 23 into a trunk... you need to make two vlans on port 23 and then bridge them into appropriate networks... ... then do the same on the basebox. Post your export and I can try to modify it appropriately if I have a chance.... right now you need to do it with bridges, since the CRS switch chip is mostly non-functional. In the 6.12 release coming out it will be fixed.
