Interfaces lose IPv6 after DSL reconnect

[skywalker007]

Scenario:
Vigor 165 modem mode
OPNsense runs pppoe on WAN and tags VLAN 7 (Deutsche Telekom)

I am currently having the problem that my VDSL is a bit flaky and loses sync at least twice a day and rebuilds the DSL connection.
When that happens, all my interfaces lose their IPv6 address (all configured to track WAN if).
This can be solved by manually navigating to Interfaces->overview->WAN and hit the "reload" button.

Is that a known issue?

thanks! Till

Am I the only one having this problem?
I still lose all IPv6 connectivity after automatic pppoE reconnect. I manually need to reload ppPoE to get IPv6 connectivity back. Any hint? Is that a timing issue maybe?
