This turns out to be relatively<\/em> easy providing that you configure the addresses within the container rather than within the container configuration. At least it looks good to go so far (I’ve been mistaken in the past).<\/p>\n\n\n\n The container configuration is quite simple :-<\/p>\n\n\n\n Note that the bridge interface (br0<\/em>) may be different. Also note that there is no lxc.net.0.ipv4.address<\/em>, lxc.net.0.ipv4.gateway<\/em>, lxc.net.0.ipv6.address<\/em>, or lxc.net.0.ipv6.gateway<\/em>.<\/p>\n\n\n\n The configuration within the container is dependent on what userland you are running, but for Debian (and Ubuntu if you’re not using Netplan) :-<\/p>\n\n\n\n Not sure quite which options are required but having all of “privext 0”, “accept_ra 0” and “autoconf 0” does mean no additional autoconfigured IPv6 addresses.<\/p>\n\n\n\n (And no the part number of this post isn’t anything more than a joke)<\/p>\n","protected":false},"excerpt":{"rendered":" On previous occasions (yes that does mean more than once) I have messed around with the network configuration of containers to get :- A consistent behaviour.
