      I'm troubleshooting some ISP DHCP6 issues. I'd like to look at the WAN DHCP6 lease info but I can't find where it is stored (or a command to display it).

      Also, is it possible to force a DHCP6 refresh for an interface (the WAN in my case) via some command? I can do it by toggling the WAN interface to disabled and then back to enabled in the GUI, but that disrupts IPv4 traffic, which I want to avoid.

        You should see that info in the dhcp log under the dhcp6c process.

        To get more info there enable 'DHCP6 Debug' in System > Advanced > Networking.

          This could be

          /usr/local/bin/php-cgi -f /etc/rc.newwanipv6
          

          Note : haven't try this myself.

          Btw : when I check the ( Status > System Logs > DHCP )

          I see that the DHCP6C renews very often - every 10 minutes ( 😵 ) or so.
          Not sure if this is normal. The DHCP6 server is in my ISP box, that's the one handing out "20 min" leases ... Not something I can change.
          The WAN IPv6 and prefix didn't change for the last 9 months or so ( ouf ...).

          No "help me" PM's please. Use the forum, the community will thank you.
          Edit : and where are the logs ??
