VPN에 연결하지 않으면 다음과 같은 결과가 나타납니다(모든 답변은 FQDN google.com에 대한 다른 IP 주소입니다).

그러나 VPN에 연결하면 답변이 변경되어 일부 DNS 서버의 IP 주소에 대한 답변도 표시됩니다.

나는 예를 보여주고 있지만 google.com
조회하려는 모든 URL에서 이런 일이 발생합니다. 그리고 이것이 증상입니다. 실제 문제는 다른 명령(예: curl
)이 요청할 때 확인 목록에 있는 무작위(?) IP를 사용하고 때로는 요청이 첫 번째 IP로 이동하여 성공적으로 실행되지만 다른 경우에는 요청이 종료된다는 것입니다. 올바른 IP 대신 DNS 서버로 연결됩니다.
지금은 어디서 문제를 확인해야 할지 모르겠습니다. 문제가 WSL, Windows 네트워킹, VPN의 DNS 서버 구성 오류인지는 알 수 없습니다. 따라서 어떤 종류의 도움이라도 대단히 감사하겠습니다.
추신: Windows의 해상도는 VPN이 연결된 상태에서 직접적으로 잘 작동합니다. 문제는 WSL 내부에만 있습니다.
편집: 디버그 출력 추가. 조회에서 WSL 인터페이스 게이트웨이를 이름 서버로 사용할 때 레코드 Authority
가 Additional
병합되는 것처럼 보입니다 .Answers
nslookup -debug google.com
WSL2 시스템의 출력입니다 .
이 명령은 WSL 게이트웨이를 네임서버로 사용해야 하며 요청을 VPN 네임서버로 보냅니다.

편집 2: WSL용으로 생성된 내부 DNS 서버인 내부 Hyper-V DNS 서버인 Windows 인터넷 연결 공유(ICS) 문제와 관련된 것 같습니다.
많은 사람들이 이 문제에 대해 불평하는 WSL의 GitHub에서 공개 문제를 발견했습니다.
