It would be nice to be able to send DHCPv6 messages to a PacketFence server which has an IPv6 address on management.

Reading the code, it seems that we only send traffic to IPv4 nodes:

packetfence-dhcp-forwarder/dhcp-forwarder/main.go

Line 50 in f4e8b89

udpAddr, err := net.ResolveUDPAddr("udp4", host+":"+port)

The default "Filter" certainly needs to be adjusted too

packetfence-dhcp-forwarder/dhcp-forwarder/DHCP-Forwarder.toml

Line 4 in f4e8b89

Filter = "udp and port 68 and ((udp[250:1] = 0x3) or (udp[250:1] = 0x5))"
