The strange thing > is that perfdhcp worked perfectly for ipv4. => DHCPv4 uses (by default, you can change the service socket type) a BPF/LPF/etc socket, DHCPv6 uses standard UDP.

PS: you can have a kernel filter (ip6tables on Linux) which drops incoming packets. Usually tcpdump/wireshark/etc can see them but they are not delivered to the server. _______________________________________________ Kea-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/kea-users
