Mr.win7 Posted February 28 Share Posted February 28 (edited) Our ISP will assign a new ipv6 prefix for the home network periodically, and also do it when the router restart. Every time the prefix changes, From dhcpcd log, Unraid will set the route to right value but won't update its own ip. I have to restart the unraid server as a workaround. Any approach to prevent it? I'm using 6.12.6. I tried both SLAAC and DHCPv6 for my router and none of it works for unraid, while the other systems (Windows and Debian) works well. The diagnostics is attached. tower-diagnostics-20240228-2308.zip Edited February 28 by Mr.win7 add extra info for network config Quote Link to comment

JorgeB Posted March 12 Share Posted March 12 I've asked @bonienlto take a look when he can, since basically only he can help, but he has been unavailable lately, so you may need to wait a little longer. Quote Link to comment

Thanks JorgeB and bonienl! I've suffered from the issue for a really long time. The behavior about IPv6 was changed for several times and it become worse each time(sigh Quote Link to comment
KluthR Posted April 18 Share Posted April 18 (edited) Same issue here. Unraid does not pick up the latest prefix from RA. This dynamic prefix shit for private customers is a pain... Edited April 18 by KluthR Quote Link to comment

KluthR Posted Sunday at 08:46 PM Share Posted Sunday at 08:46 PM In current .10 release I also see permanent DHCPD6 renew messages, didnt remember the exact term, hold on… dhcpcd[1128]: eth0: requesting DHCPv6 information every ten secs. But maybe its because I habe only Stateful RA enabled router? Quote Link to comment
bmartino1 Posted Sunday at 11:24 PM Share Posted Sunday at 11:24 PM (edited) my router does ipv6 porperly. but here is the corect command to release and renew form termainl ipv6 address. Tested: ip -6 addr flush dev eth0 ifconfig eth0 inet6 0 Replace eth0 with the interface you need to have renewed. In my case it vhost0 so eth0 becomes vhost0 Edited Sunday at 11:25 PM by bmartino1 Quote Link to comment

Mr.win7 Posted 3 hours ago Author Share Posted 3 hours ago Hi @JorgeB and @bonienl, could you please share us the progress or plan about the issue? Though we can manually flush the IPv6 address, I still want the Unraid to flush it automatically. Quote Link to comment
