두 개의 인터페이스로 IPv6 라우터를 설정했는데 왜 구성된 LAN -> 'NET 액세스만 작동하지 않습니까?

두 개의 인터페이스로 IPv6 라우터를 설정했는데 왜 구성된 LAN -> 'NET 액세스만 작동하지 않습니까?

저는 Fedora에 Linux 방화벽/라우터를 설정하고 있습니다.

IPv6를 작동시키려고 합니다.

내 간단한 네트워크는 다음과 같습니다

내부 IPv6가 실행 중입니다.

LINUXROUTER에서 'NET에 액세스하면 정상적으로 작동합니다.

하지만 마지막 부분인 LAN(데스크톱)에서 "네트워크"로 이동하는 부분을 놓쳤습니다.

현재 세부정보는 다음과 같습니다.

즉, ping6

제대로 작동하려면 무엇이 빠졌나요?

나에게 필요한 라우팅, 규칙, 정책 ​​또는 기타 시스템 구성입니까?

감사해요,
