Description

This might be related to #4455.

I am seeing the same radvd spam under System / Routing logs:

Aug 27 20:43:00    radvd    53790    interface gif0 does not support broadcast
Aug 27 20:43:00    radvd    53790    do you need to add the UnicastOnly flag?

I don't know how to set that flag from the radvd configuration page.

Unlike #4455, this is not for a VPN connection, but a GIF interface for an IPv6 tunnel.

I found out the issue. I had to:

  • change the tunnel IF IPv6 from None to Static
  • access the radvd page for the tunnel IF
  • change from Managed to Disabled
  • revert the tunnel IF IPv6 to None.

This means that there is a bug in pfSense where, even though an interface has its IPv6 address assignment disabled, and the DHCPv6 and radvd pages are hidden, radvd can still be enabled and non-configurable.
