Another option for you would be to get a device that is compatible with VLANs on DD WRT. However, I dont prefer taking this approach since if something breaks, it might be a PITA to fix it.
Instead, why not get a cheap Athlon or Pentium combo with ATX support, and some LAN cards and run Zentyal on it? You get the router, the NAS and some more features.
