What mode does the Cr200a gate way use to issue ipV6 address in passthru mode? dhcpv6 or slacc and the prefix size? i am trying to get a unify udm se to issue ipv6 addresses to clients on default vlan. IPv4 works perfect, but i'm unsure of the settings for ipv6 .
Solved! Go to Correct Answer
After logging into the Unify UDM SE via ssh and viewing the port I discover DHCP v6 is broken. I configure the Cr200a gateway for stateless mode for IPV6 and then into passthru mode. I then set the UDM internet port to single network and slack for IPv6. This should work for Ask, ARC ect. Hope this helps those that don't want to double nat ipV4. Other than Verizon enablig DHCP V6 and giving us a /56 "i would not hold my breath" this should work with other devices llike OPsense or other routers that allow these setting. Spent a day figurung this out.

IPV6 passthrough is not supported (yet?) on the ASK-NCQ1338FA router. I have a feeling your router (CR200A) is the same.
