OPNsense & Draytek Vigor 165: Error messages in logs & firewall

[ripcord9058]

Hello everyone,

I have recently switched to a combination of Draytek Vigor 165 and OPNsense. The Internet runs via PPPoE so far. I have a VDSL connection with O2.

I mainly want to understand where the following messages/errors are coming from and if I can fix them.
If you need any further information, please let me know.


The devices are connected as follows:


I have now noticed two things in the OPNsense interface:

• On the one hand, I have a constantly recurring error in the logs under System->Log Files->General
  /usr/local/etc/rc.newwanipv6: Interface '' (igb2) is disabled or empty, nothing to do.
  igb2 is the wan interface.
  
  
• The firewall seems to constantly block a broadcast message from the Draytek modem. The modem is running in bridge mode.
  According to the NDP table, the source IPv6 corresponds to the Draytek modem. I have deactivated the logging of Default block and Default pass.
