The objective of the document is on how to setup LXC container which can connect to external networks. There are multiple network modes that can be used in setting up LXC.
By default, the lxc-oracle template script sets up networking by setting up a veth bridge. In this mode, a container obtains its IP address from the dnsmasq server that libvirtd runs on the private virtual bridge network (virbr0) between the container and the host. The host allows a container to connect to the rest of the network by using NAT rules in iptables, but these rules do not allow incoming connections to the container. Both the host and other containers on the veth bridge have network access to the container via the bridge.
