With recent changes to the listening socket code in pve-manager the proxy daemons now usually bind to '::' and ipv4 clients are read as v4-mapped-v6 addresses [0] from ::ffff:0:0/96. This caused the allow_from/deny_from matching to break. This patch addresses the issue by normalizing addresses from ::ffff:0:0/96 using Net::IP::ip_get_embedded_ipv4 (which roughly splits on ':' and checks if the last part looks like an ipv4 address). Issue was originally reported in our community forum [1] [0] https://en.wikipedia.org/wiki/IPv6_address [1] https://forum.proxmox.com/threads/my-pveproxy-file-doesnt-work.83228/ Signed-off-by: Stoiko Ivanov <s.ivanov@proxmox.com>
