Dear Patrick,

congratulations! Now as you seems to have a running setup, you'll probably want 
to keep it. Said that, I want to give 5ct more on your statement of the fixed 
IP and MAC you have to use:

Maybe you have pay attention of the MACs used by the veth's attaching to the 
software bridge: It's a that the brige is using the lowest-numbered MAC of the 
attached devices as the MACs of the outgoing packets (see e.g. 
https://backreference.org/2010/07/28/linux-bridge-mac-addresses-and-dynamic-ports/).
 I don't know about the current state of LXC about this, but in my enviromment 
I let the container management script assign a certain calculated, 
"high-numbered" MAC (some prefix and a calculated part derived from the 
containers IP, in concrete: a.b.c.d -> 00:50:C2:bb:cc:dd (hex)).

In your special hoster-driven situation, it might be necessary to use for the 
vet's a MACs with an higher number as the one to be used with your fixed IPs to 
get the expected MACs to be used for the outgoing traffic. If this was the core 
issue, it may solve the "DNS" problem as well as the "http get"-problem.
