桥接模式无法联网:本地网络接口桥接协议、虚拟网络编辑器桥接接口均无问题,ip由dhcp动态配置,仍无

2020-04-27 20:18发布

问题:

由NAT模式切换为桥接模式后出现无法连接网络,无法ping通主机的问题
NAT模式可正常联网

检查本地网络接口桥接协议

检查虚拟网络编辑器桥接接口

检查网络配置

[root@hawava network-scripts]# cat ifcfg-eno16777736
TYPE="Ethernet"
BOOTPROTO="dhcp"
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"

后尝试更改为静态ip,仍无法解决问题,求助!感激不尽!

回答1:

改为静态IP和网关要配置与主机IP同样的网段与网关,先查看你主机windows网络信息。Linux 网络配置文件,dhcp改为static
