> For customers where you bring your own cable modem or have one of the above in bridge mode we have enabled IPv6 support for you as well.  However, your router behind the modem must be running software and configured with IPv6 support.  Specifically, your router needs to be support stateful DHCPv6 for IPv6 address and prefix acquisition.  We have received a number of reports from customers that the Juniper SRX does not appear to properly support IPv6.  We are working with Juniper and also recommend that you reach out to Juniper as well.

Care to share scenarios where the SRXs do not perform well with DHCPv6? 
Any specific model?
