IPv6 Router Advertisement seems to fail

Hello

I have a strange issue with my UTM. For now reason it seems like the Sophos stops broadcasting it's router role for IPv6. It simply stops routing IPv6 Prefix and even with a static assignment it is not routing any IPv6 Traffic anymore.

However: The problem seems resolved when I turn router advertisement off and on again (on any interface). But the problem reappears after about 4-5 days without any other changes to the UTM and it feels like this should not happen.

This happens with and without IPv6 DHCP.

  • Update on this issue, it still exists.

    A renew of external interface does not update IPv6 connections. I  might not have waited long enough after disabling IPv6 then re-enabling it to cause IPv6 update on the external interface. I restarted the UTM and the a new real external address was assigned.

    This is the same issue as on the XG, so looks like there is a common driver issue that needs to be addressed. (just to add to Ben's complaint)
