Fedora 32에서 게이트웨이 192.168.31.1을 ping할 수 없는 이유는 무엇입니까?

내 현재 IP는 192.168.31.77이지만 이제 게이트웨이 192.168.31.1에 ping을 보낼 수 없습니다. 이것이 내가 사용하고 있는 네트워크입니다 ifconfig.

게이트웨이 주소를 ping할 수 없는 이유는 무엇입니까?

답변1

문제는 게이트웨이가 있는 네트워크인 동일한 네트워크( )를 공유하는 br0데 있습니다.wl01192.168.31.7/24

다른 네트워크를 할당하면 wl01문제가 해결됩니다.

192.168.31.1wl01올바른 장치를 통해 명시적인 경로를 생성하거나 브리지에 추가해 볼 수도 있습니다 .
