[ale] Virtual networks

[Dustin Strickland]

Thanks for the link, however I am already somewhat familiar with 
bridging outside the context of virtual interfaces. I already have a 
bridge set up for each of the physical eth controllers. Reading back 
over my initial post, it looks like I wasn't too clear about what I was 
asking.

So, the VLAN I have set up now was created through virt-manager. I would 
like to access this from outside the host machine(and away from home), 
hence a VPN. From what I can tell about OpenVPN, it requires a bridged 
interface. In order to make one for the VLAN I have, I would need to 
define the VLAN itself in the interfaces file in order to keep the 
bridge from trying to come up before the interface it's bridging 
exists(I assume?) which I do not know how to do. Reading about 
manually-created VLANs produces curious lines like "iface eth1:200 inet 
static" which appear to be bound to a physical interface. Is this what 
is going on, and is that necessary for an isolated network?
