https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239417 --- Comment #5 from Yuri Victorovich <yuri@freebsd.org> --- (In reply to Eugene Grosbein from comment #4) Hi Eugene, I am doing this in the context of the containerization application that I am working on, yet unannounced (https://github.com/yurivict/crate). It is alre= ady functional, but needs networking and configuration management bits to be ad= ded or fixed. It runs programs and services in jails, and connects them to network dynamically using firewall rules or bridges. The main mode of connectivity is the "blend" mode when it blends with the h= ost IP address using epair(4) and firewall rules. This doesn't involve creation= of IP addresses, and I have it working, except for some minor details. The secondary mode is the "lan" mode which creates a dedicated LAN IP addre= ss for each container. I asked this question originally for this mode. Your suggestion about moving the IP address to the bridge makes sense. The proce= ss looks a bit more invasive than I originally thought it would be, because it would involve altering the network settings, moving the IP to another inter= face for the life of container or all containers and then moving it back, as per your advise. I will try this. This is only needed to find a spare LAN IP to allocate, and is not needed for subsequent container operation. Also this "= lan" mode isn't strictly necessary because the "blend" mode should satisfy most = use cases. I just came up with it, and thought that it would be interesting to implement it too. Thank you for your help! Yuri --=20 You are receiving this mail because: You are the assignee for the bug.=
