Need Clarification Before Installation

I've been poking around at setting up an Untangle box in route mode for my house/home office. Mainly for experience sake since a UTM is a bit overkill for any home office setup. Anyways - I've been reading whatever I can but a few items are still a bit unclear to me:

1) Virtualization. I know it's no longer officially supported, but I've read numerous posts about people putting Untangle in a VM and being fine. I have a Citrix Xenserver running that has 3 VMs on it. They are all fairly low-intensity VMs. If I put it in a VM gave the Untangle VM say 4 GB of RAM, and gave it highest priority on the CPU across all cores (quad core Athlon II x4 @ 3.0GHz) would I be fine, or is the in-efficiency with VMs more low-level than resource allocation? Keep in mind, this box would be handling traffic for 5-10 clients max at any one time.

2) VLANs. I've read a lot saying Untangle doesn't support vLANs, but I've read just as much from people saying that they have numerous vLANs running just fine with Untangle. So...:confused:

2a) If Untangle doesn't directly support vLANs then could I, for example, connect a managed switch to Untangle and have that switch then break down it's network segment into individual vLANs without it causing all hell to break loose?


Like I said, just looking for some clarifications before I decide which UTM software to go with.

1.) VMs aren't supported. Xen specifically has tools that you can't install. However, if you know Xen well enough, it works just fine.
2.) Untangle strips VLAN tags as things pass through it. This doesn't mean it can't do VLANs it just means you have to use aliases, or separate interfaces for each VLAN.
2a.) (3?) That's exactly what you do.

Untangle is an edge device. VLANS have no real place on the edge. There are a few cases where they can be useful, but to be honest if they are being useful, you're probably large enough to be using managed layer 3 switches anyway. And if you're doing that, just create a new subnet between the switch and Untangle, make UT a router, and move on.
