It's an really interesting solution. I've to look at the VLAN technic, 
because I've never used it.

One thing was, that nobody - only the HN - could change the IP for a CT. 
This issue couldn't be solved by VLAN or veth, so I thought to use 
venet.

Now I think I'll prefer the bultin veth technic to solve my problem 
right now.

Thanks a lot
