i have comcast, and i use dhcpcd for ipv6.

replace rge0 and vport0 with your wan/lan interface..

# /etc/dhcpcd.conf
ipv6only
duid
persistent
vendorclassid
option rapid_commit
option interface_mtu

# make dhcpcd not touch nameservers.
nohook resolv.conf

require dhcp_server_identifier
slaac private
allowinterfaces rge0
interface rge0
ipv6rs
iaid 1
ia_na 1
ia_pd 1/::/64 vport0/0/64
