Hi, I have a friend who's reported my than ifupdown2 had been installed by default on pve 8.1 upgrade.
I think it's because pve-network have "Recommends: ifupdown2". This proxmox server was installed with debian iso, with default ipv6 on interface (auto eth0 inet6 ..). Seem that it have impacted the slaac config. (I had double check some months ago ipv6 with ifupdown2, all was ok, but maybe default accept_ra is different if ifupdown2, not 100% sure ye) _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
