So you can or can not hit the internet? It's not clear, what your problem is exactly
It's also not clear, which one you mean by 'lxc host'.

Do you really mean the machine, where containers are running, or lxc host is actually the guest?

You don't need to use lxc.network.ipv4, if you setup the network from the container.
