[Pdns-users] Screwy pdns configuration.

[Peter Nunn]

Peter you are a champion.

Turns out to have been an openvpn connection that had partly come up giving me a default route back to the host that happened to have pdns running on it (also the vpn end point).

Get rid of that route and all is now good again.


THANKYOU.

Would never have twigged without your help

Peter.
