Daisy Chain Orbi Routers w/ IPv6?
Wondering if anyone has successfully Daisy Chained two Orbi routers and had working IPv6 on the second router.
I understand that having one router 'behind' another router is not a recommended p...
Thanks for taking the time to respond. Will look to see what Spectrum publishes about IPv6. When I look at the router IPv6 page, there does not seem to be much useful information.
I can see the IPv6 of my router (/128 prefix), and the IPv6 assigned to my PC, the router LAN interface, and some other devices on the network.
2605:e000:3fc0:3e:d2:44a9:3c1a:e199/128 - router WAN
2603:8000:403:bd7c:a204:60ff:fe1c:239/64 - router LAN
2603:8000:403:bd7c:ff9d:7e3f:f1c1:1dd9 - PC
2603:8000:403:bd7c:6ecd:d6ff:fe02:3ea9 - WAN interface on the RBR750
Somehow the PC seems to generate 'temporary' IPv6 addresses:

Have you tried setting the RBR750 ipv6 setting to pass-through mode?
That should make it work like an ipv6 switch (leaving the routing up to the RBR50).
Thanks for responding. Unless I misunderstand, putting the 750 in "pass-through" mode appears to be equivalent to setting the 750 to Access Point (AP) mode rather than router mode.
AP mode is certainly what would be recommended, but my goal is to figure out how to get the 750 to support IPv6 in router mode.
(Actually, I believe that I did select "pass-through" mode and it seemed to have no positive effect.)
grrrr. This all started because of a post on the Forum about firmware updates having 'broken' IPv6 on the Orbi 850 and I wanted to be able to contribute "something" to the discussion.
I considered designating the RBR750 as the DMZ server, thinking perhaps it would get IPv6 from Spectrum (in addition to the primary RBR50 router).
.......... this is SO frustrating!!!

Yes, for ipv6. ipv4 would still route.
The behavior I'd expect is that the 750 would have no ipv6 address, but the 750 clients should get ipv6 addresses. If you don't know what to look for, you could easily conclude that it had no effect.
but my goal is to figure out how to get the 750 to support IPv6 in router mode.
Understood. That would require that
- you get a /56 or /60 address block from Spectrum
- you figure out how to assign one of the /64 subnets to the 750.
Trying to divide a /64 address block doesn't work - several core protocols break if you attempt it.
So the passthrough mode does have some value - it's the only path if you get a /64 address block from your ISP.
I considered designating the RBR750 as the DMZ server
Does the RBR50 let you designate an ipv6 address as the DMZ?
There is no port forwarding, so the only potential benefit of an ipv6 DMZ would be to allow unsolicited inbound flows to connect to the designated server. I don't see how that helps with double-routing.
this is SO frustrating!!!
Agreed. One aspect is that Netgear isn't giving much guidance on exactly what their ipv6 controls do.
