Nest Protect Requires IPV6

NashBrydges

Hi,

I am trying to setup 2 Nest Protect at my home and running Sophos XG Home. During setup, I've come to learn that in order for them to communicate together (so that if one alarm goes off so does the other) I need to have IPV6 enabled on my Sophos XG. Sophos is handling all of the routing on my network. The Nest devices need to obtain a DHCP IPV6 address and they use the IPV4 to connect to the outside.

Question is, I have no idea how to turn this on or enable DHCP for IPV6. Hoping someone here can point me in the right direction.

I've located the IPV6 DHCP settings on my LAN Interface but what would I enter for a IPV6/prefix or gateway IP? Is that all I have to do and the Nest devices will get an IPV6 address?

By the way, the Nest devices are connected via a VLAN on my LAN interface (not sure if that changes anything). Any help would be appreciated.

    Hi Nash,

    I've had the Nest Protect for about 5 years along with the Nest thermostats.  They do use link local IPv6 to communicate with each other on their own private little network.  They use IPv4 to communicate via the internet.  I only configured IPv6 a year ago on my network and my nest protects worked without issue before that.  Perhaps the newer models are different?

    Hi  

    I have the second gen Nest Protect.

    Do you have yours setup with Sophos XG at the network edge and handling the routing duties? If so, how did you set it up so they can talk to each other?

    I don't have any special configuration for the Nest products (no special rules).  While I do have IPv6 setup for my home network not all of the Nest products use it.  This is because Android does not fully support IPv6.  Android only supports stateless communications.  I have no need of stateless.  My IPv6 is configured to dish out a range of IPv6 addresses depending on who/what is connecting.  Interestingly, I contacted Nest about the IPv6 issue sometime last year and since then my Nest Thermostat now properly connects to my IPv6 network and is assigned an IPv6 address.  It is the only Nest product that does.  The Nest Protects on my network are only assigned IPv4 addresses.  I can still access the Nest Protects through the Nest app.  I assume that they are reachable through the IPv4 network.

    Best regards.
