Pfsense not responding to ISP's Neighbor Solicitation



  • My iPv6 connection keeps dropping, after packet capture I see a Neighbor Solicitation (udp135) from the ISP router, but I'm not seeing any Neighbor Advertisement (UDP136) response from my Pfsense FW. I'm running 2.4.1




  • What does your provider say how to configure your WAN port?
    What are your actual settings of the WAN interface?
