I'm trying to configure DHCPv6 relay for a few interfaces. One of the interfaces works perfectly, but three others doesn't work at all.
On the interface where the relay is working I can see the traffic flow in the traffic log, but on the interfaces where it doesn't work I see nothing at all in the log. I log all dropped packages.
I ran a packet capture on all stages on one of the non-working interfaces, and I can see that the firewall receives the DHCPv6 packet on ff02::1:2 from the client in the receive stage, but I can't see it in the firewall stage or any other stage.
I found something interesting in the dhcpd.log:
May 23 13:28:27 pan_dhcp6_handle_packet(pan_dhcp6.c:94): receive packet on interface 267 length 36 message type 11
May 23 13:28:27 pan_dhcpd_relay6_handle_packet(pan_dhcpd_relay6.c:156): interface ethernet1/5.1023 is not on
(I found similar messages for the other interfaces)
What does it mean that the interface "is not on"?
All other traffic works, including a DNS proxy on the same interface.
