Is IPv6 support possible on a Cisco DPC3939B in bridged mode?

Hi folks,

I have a DPC3939B setup in "bridge model".  Is there a way to get IPv6 set up, configured and working in this mode?  Maybe it's already there and I just don't have the configuration of my Ubiquiti Unifi Security Gateway (USG) set up correctly.

How would I verify the IPv6 settings are correct?

Thanks,
