IPv6 DHCP delegated prefix issue

Ed R

Hello All,

Due to a line change (ASDL to VVDSL)  I got new IP addresses from my ISP. These were and are fixed addresses but I need a DHCP client to get them.

The issue has to do with IPv6, IPv4 is working fine. At the line a Draytek Vigor 130 is installed in bridge mode and VLAN stripping is disabled.

In UTM the WAN side network adapter is set to PPPoE, the box "Static PPPOE IP" is not checked and at the advanced section the correct VLAN is stripped. So far so good. BUT, when I enable IPv6 using the switch in the global section of IPv6 the following is displayed:  Native over WAN (DSL)
Delegated Prefix: 2001:980:xxxx::/48. Seems good except for the IP address. This is my old prefix and not the new one belonging to the new line. This must be an issue in UTM because when I connect a simple hardware router to the Vigor modem I get the right new prefix delegated and IPv6 is working.

The UTM software version is: 9.351-3

Please help me with this issue.

Thanks in advance.

Ed.

    Try as root:

    rm /var/chroot-dhcpc/var/db/*.leases6

    /var/mdw/scripts/ipv6_watchdog restart

    Does that help?

    Otherwise please post relevant log line from IPv6 log.

    There was 1 file with the .leases extension. I opened it and the old prefix was in. Then I did serveral things:
    1. I renamed the file and run the script. That didn't help
    2. I rebooted the computer. That didn't help
    3. I renamed the file back to the original name and put the new prefix in place and then rerun the script. That didn't help. I still get the old prefix at the IPv6 Global page. So it should be stored elsewhere.
    Below you will find the IPv6 log from the moment I put the switch IPv6 to ON till the moment I switched it OFF again. Remarkable are the lines with eth1 in it. As eth1 is the LAN adapter and eth0 is the WAN adapter. I hope this does ring a bell
