BIND doesn't properly restart upon bouncing of LAN interface (pfSense 2.3.3_1)



  • Hello

    Using pfSense 2.3.3_1. I have the BIND package installed as a DNS server for my LAN, using some BIND specific features, etc.

    One issue I'm having is upon the LAN interface going down (doesn't happen often but it's still an issue nevertheless) the BIND server doesn't react properly to it and doesn't accept queries from clients, etc.

    Here is the relevant output from the named logs.

    Thanks



  • Seems like old or other process are still using the 53 port.



  • Ah. I have DNS resolver/forwarder disabled though.

    Could it possibly be a phantom BIND instance of a sort?

    Will do more tests later.
