Upgrade to 19.7 lost ipv6

[nivek1612]

After upgrading to 19.7 I still get an IPv6 address on LAN and can ping this IPv6 address from remote locations

However no devices on LAN are being given IPv6 address

I noticed dhcp6d server was not running and is stopped after each reboot until manually started

But even after manually starting dhcp6d server not clients are being given IPv6 address

Cant see anything obvious on logs

EDIT: it appears there is no /etc/dhcp6v.conf file being created anymore suspect thats not helping

EDIT2: clients that had IPv6 before the update have kept them and function correctly although I suspect they will lose that connectivity when the lease expires 


EDIT3: See my workaround in my last post

Hi Kev,

Can you check out this command for me?

# grep -i ipaddrv6 /conf/config.xml

Though, for now it seems a wee bit odd it would change behaviour there.


Thanks,
Franco

root@home:~ # grep -i ipaddrv6 /conf/config.xml
      <ipaddrv6>dhcp6</ipaddrv6>
      <ipaddrv6>track6</ipaddrv6>

FYI this is my french system which uses track WAN for IPv6

My UK system is still on 19.7.RC1 using a fixed IPV6 and is working fine

WORKAROUND - TEMP FIX


If I go to LAN and tick Allow manual adjustment of DHCPv6 and Router Advertisements under the track interfaces section

Then configure the dhcp6 server via

Services: DHCPv6: [LAN]

I tick enable Server and set the range to the full available range

and Router Advertisements via

Services: Router Advertisements: [LAN]

I select Assisted

I believe these are the automatic defaults anyway when using Track interface without manual adjustment 

I can create a functioning IPv6 system again so suspect the error is simply a config setting not being honoured in automatic mode for Track Interface
