>From what I understand , there is two options : 

- lxc configuration file 
- network config file into the container 

I don't think you can mix both and you are better to stick with one solution .

Objet: Re: [lxc-users] Container doesn't connect to bridge 

I already have networking setup in the container: 
root@thinkweb:/# cat /etc/network/interfaces 
auto lo 
iface lo inet loopback 

auto eth0 
iface eth0 inet static 
address 192.168.54.110 
netmask 255.255.255.128 
gateway 192.168.54.1 

When I add lxc.network.ipv4.gateway to the config it now works. Why would 
adding the gateway to the config work, but not in interfaces. I've never needed 
to add the gateway to the config before.

I set the virtual switch that the host uses to promiscuous mode and I can ping 
the gateway and other machines on my subnet from the container, however I still 
cannot get to the outside world:

Is this because of my routing table on the container?

Obviously. 

You either need "lxc.network.ipv4.gateway" (see "man lxc.container.conf"), or 
setup networking inside the container (e.g on /etc/network/interfaces)
