Thanks a lot.
I tried the config and it's *almost* working.
When pinging the output from the container : packets are going out with
the good MAC.
However, nothing in return.
From tcpdumps I figured out that my parent host is not responding to
arp for the container IP.
How do I tell my host to respond to those arp queries ?
I found some post on how it's done with openvz venet :

Any clue ?

I finally made it work with veth mode, and a bridge on the host, but it's
frustrating.
And I have to manually generate and allow all mac adresses (required by
my
server hoster).
I'd just comment on this one first.
What is your hoster like? Is it like serverloft where you can buy
additional IPs (one IP, /32 each) and the hoster would route the
additional IPs thru the server's primary IP?
It's Online.net (french)
I think it's exactly the way you describe.
If yes, then you can use a custom veth + bridge + routed mode where
the hoster's switch/router will only see one MAC.
That would work I think. Do you have some doc/exemple on that ?
I use ubuntu precise on both server and container. On the server:
### snippet of /etc/network/interface ###
auto br0
iface br0 inet static
address 192.168.124.1
netmask 255.255.255.0
bridge_ports none
bridge_maxwait 0
bridge_stp off
bridge_fd 0
up ip route add PUBLIC_IP_OF_CONTAINER/32 dev br0 || true
###
... and make sure /proc/sys/net/ipv4/ip_forward is 1 (lxc-net ubuntu
package should already set that)
### snippet of container config ###
# Network configuration
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.hwaddr = 00:16:3E:D8:FF:13
lxc.network.veth.pair=veth-CONT1-0
###
on the container:
###
auto eth0
iface eth0 inet static
address PUBLIC_IP_OF_CONTAINER
netmask 255.255.255.255
up ip route add 192.168.124.1 dev eth0
up ip route add default via 192.168.124.1
