RickiRolled Posted March 15, 2024 Share Posted March 15, 2024 Hi, i am days new into using starlink so i'm just finding my feet I have bypassed the Starlink router to use my own Nighthawk xr1000 but i'm struggling to setup ipv6 the options i have available are "auto detect, 6to4tunnel, passthrough, fixed, DHCP, PPPoE, Auto config, 6rd tunnel... Ithe only one i have some success with is passthrough but it makes my devices drop internet connection in seconds. When i chose auto configure ipv6 addresses are assigned but only for minutes and then gone again. Can anyone help direct me? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 15, 2024 Administrators Share Posted March 15, 2024 Use the DHCP option, does that work at all? Link to comment Share on other sites More sharing options...
RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 it assigns an ip to "Router's IPv6 Address On WAN" but not available on "Router's IPv6 Address On LAN" Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 15, 2024 Administrators Share Posted March 15, 2024 That's all you need, you don't need LAN IPv6 - LAN IPv6 is just a way to assign local private addresses to devices so IPv4 is fine for that. If you then do an IPv6 test does it work? Link to comment Share on other sites More sharing options...
RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 Tests dont detect an ipv6 address Link to comment Share on other sites More sharing options...
RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 I don't know if this information is of any use to you but all i keep reading is starlink use a prefix of 56. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 15, 2024 Administrators Share Posted March 15, 2024 Try the 6to4 tunnel and see if that works, does auto detect not do it at all? Is the XR in the DMZ on the Starlink router? Link to comment Share on other sites More sharing options...
RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 I'll give the 6to4 an go then, auto detect puts it into passthrough mode which does give me an ipv6 address but it cycles in seconds so nothing wired or wireless remains connected. The starlink router is in bypass mode so it's just acting as a power source for the satellite. Link to comment Share on other sites More sharing options...
RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 no ipv6 address with 6to4 it gave me a ipv6 lan address.. am i correct in thinking the router is getting a ipv6 address but not assigning them to devices? Link to comment Share on other sites More sharing options...
RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 Just plugged in my old Asus RT-AC86U put ipv6 on Native connection DHCP-PD Enabled, stateless configuration and auto DNS server setting and ipv6 is working absolutely fine Link to comment Share on other sites More sharing options...

RickiRolled Posted March 15, 2024 Author Share Posted March 15, 2024 So when i plugged the XR back in it gave me a ipv6 for around 3 minutes then dropped it again.. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 15, 2024 Administrators Share Posted March 15, 2024 Make the IPv6 work then grab the logs from the System Information page when it stops working please and I can see if there is anything in there that points to the issue Link to comment Share on other sites More sharing options...
RickiRolled Posted March 16, 2024 Author Share Posted March 16, 2024 i've tried for hours to replicate it with no luck. i came across this though i didn'y know if it might be useful.. "Starlink uses DHCP for IPv4 and SLAAC/DHCPv6-PD for IPv6 to assign the router or client connected directly to the Starlink terminal an address or prefix. Starlink can only assign one IPv4 address per client. IPv6 capable routers will be delegated a /56 prefix for the router to manage." Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 16, 2024 Administrators Share Posted March 16, 2024 So you couldn't even get it to start working again? Take the Starlink out of bypass mode, put the XR in its DMZ and see if it can more consistently get IPv6 then please Link to comment Share on other sites More sharing options...
RickiRolled Posted March 16, 2024 Author Share Posted March 16, 2024 I don't believe i can get into the starlink router DMZ but overnight i tested 4 different routers.. 2 worked with ipv6 an 2 didnt.. the 2 that didnt are the XR1000 and R2... the XR1000 seems to assign itself an ipv6 address but doesnt assign an address to devices except on that one time where it did for 3 minutes and then dropped them and the R2 does absolutely nothing and gives me a strict nat type Link to comment Share on other sites More sharing options...
RickiRolled Posted March 16, 2024 Author Share Posted March 16, 2024 I found this topic on the Netgear forums which is very similar to what I'm experiencing.. https://community.netgear.com/t5/Nighthawk-Pro-Gaming-Routers/XR1000-not-able-to-keep-IPv6-Address/m-p/2150406 Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 16, 2024 Administrators Share Posted March 16, 2024 So apparently the Auto Config option is SLAAC so I think it would be best to just try exclusively with this option. Select Use these DNS and also use the DHCP server option as well. Once you've set it all up reboot it from the interface and see if it works at all Link to comment Share on other sites More sharing options...
RickiRolled Posted March 16, 2024 Author Share Posted March 16, 2024 The router gets an ipv6 wan address but no devices have an ipv6 address. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 16, 2024 Administrators Share Posted March 16, 2024 There is no real reason it shouldn't be working, I doubt it would make a difference but could you disable QoS completely from the Congestion Control menu  and see if that helps please?

RickiRolled Posted March 16, 2024 Author Share Posted March 16, 2024 i saw that idea on another post where they disabled QoS and then ipv6 worked and they could enable QoS after.. unfortunately i tried that and it didnt work for me Link to comment Share on other sites More sharing options...
RickiRolled Posted March 16, 2024 Author Share Posted March 16, 2024 Just for the sakes of reruling it out i've just disabled it and no difference. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 16, 2024 Administrators Share Posted March 16, 2024 It might be worth contacting NG directly about this, as its not our settings they'd more likely know the reason for it not working Link to comment Share on other sites More sharing options...
RickiRolled Posted March 19, 2024 Author Share Posted March 19, 2024 So since your last message i unplugged the XR1000 for around 36 hours and just went back to using the starlink router for the time being but Netgear responded to the ticket i opened requesting pictures of the ipv6 settings.. so i replugged in the XR1000 and for some reason without adjusting any settings it has assigned ipv6 addresses to all my devices and hasnt dropped them for over 12 hours now..

Administrators Netduma Fraser Posted March 19, 2024 Administrators Share Posted March 19, 2024 That's great to hear, thanks for the update! Perhaps the connection needed time to know the XR would be a permanent addition, that can happen sometimes with certain ISPs Link to comment Share on other sites More sharing options...
