  • Fixed Server executable (sdnsmain.exe) might not fully terminate after service shutdown / GUI shutdown request, causing problems with restarts.
  • Fixed If configured to listen for DNS requests on "any local IP address", it might send responses from a different IP address than the incoming request was sent to - causing various issues.
  • Fixed Import standard zone file function resulted in "Could not load zone file" error message for good zone files.

Build 102 - November 4th 2021

  • Improved When using random ports for outbound requests (default), received ICMP error messages on UDP resolver sockets (socket errors 10052/10054) are now processed as DNS error responses, preventing additional request resends. This reduces network traffic and improves resolver response time.
  • Improved Socket errors 10052/10054 on UDP sockets are now logged as ICMP messages (including origin IP address), and are no longer classified as errors (meaning that they no longer show up in the log, if you only log errors and warnings).
