Task: consolidate all network devices in one secure box.
All device mean Apple TimeCapsule, Router, NAS and HPServer with couple VMs.
All this staff we going to move into one single box QNAP 451.
QNAP 451 cost AUD495 and comes just with 1Gb of memory. I bought 8Gb stick for AUD48 and now able to have virtualisation inside the box. (in the future can install additional 8Gb).
I do not think you have questions how to setup timemachine and NAS (file sharing) on QNAP. Lets concentrate on VMs and router.
Router will be based on watchguard XTMv. https://www.watchguard.com/wgrd-products/utm/xtmv/overview
You can download OVF file from Fireware 11.11.1 OVF Template for new installations
The issue is that the file is not supported by QNAP VM import. You have to install VirtualBox 4, open OVF and save it again. Now you can import the OVF inside of the QNAP and configure your network adapters.
One virtual NIC will be dedicated for internet connection, another - LAN.
We can use same process to move VMs from HPServer to QNAP.
Also WatchGuard Dimension server was successfuly installed for logging and analysing.
Finally all boxes inside QNAP. Power consumtion is 28W and everithing could be backed up easely to external USB3 HDD twice a year just in case.
