OpenVPN이 CentOS 7을 통해 OVH와의 연결이 끊어지는 이유는 무엇입니까?

몇 초 후 가상 머신에서 CentOS 7을 통해 VPN에 연결한 후 연결이 끊어졌고 로그에 오류가 없습니다. 이는 CentOS 7/8에서만 발생하는 것 같습니다. OVH 문서(https://docs.ovh.com/gb/en/dedicated/network-bridging/) 추가 표지

51.195.234.254 - 255.255.255.255 eth0
51.195.234.0 - 255.255.255.0 eth0
default 51.195.234.254

또는

51.195.234.254 dev eth0
default via 51.195.234.254

/etc/sysconfig/network-scripts/route-eth0으로 이동했지만 도움이 되지 않았습니다.
