topic Re: Third party router with FTTP in Broadband https://helpforum.sky.com/t5/Broadband/Third-party-router-with-FTTP/m-p/3565538#M222606 Glad to hear you got it working, <a href="https://helpforum.sky.com/t5/user/viewprofilepage/user-id/2363809">@IanW73</a>;  I can answer some of the additional questions. IPv4 is still native and delivered alongside IPv6, i.e., "Dual Stack", rather than using any of the newer IPv4aaS technologies.  So the DHCPv4 client on the WAN is still required. Sky Talk on FTTP, as with the "Single Order" FTTC products, is delivered as VoIP directly to the ATA built in to the Sky Hub 4.  The ATA/FXS port on the ONT is not used for Sky Talk. Sky does not support the use of 3rd party ATAs for Sky Talk, so if you replace your Sky Hub 4 with an alternative, you'll be forgoing voice services.    The more adventurous of you could look at setting up your own stateful DHCPv6 PD server on your 3rd party router to sub-delegate an IPv6 prefix to the Sky Hub, as it uses IPv6 to talk to the SBC.  But this hasn't been tested and is definitely not supported.
