无法从虚拟机连接到主机网络

无法从虚拟机连接到主机网络

我有一个托管在 ubuntu 上的 centos 虚拟机,在 ubuntu 上我连接到 open-connect VPN,我想通过 centos 6.7 虚拟机使用这个 VPN。

我已经像这样设置了 Virtual Box 仅主机网络:

vboxnet0
adapter:
ipv4 address: 192.168.56.1
ipv4 network mask: 255.255.255.0

DHCP server : 
enable server 
 server address: 192.168.56.100
 server mask: 255.255.255.0
 lower address bound: 192.168.56.101
 upper address bound: 192.168.56.254

然后我配置了 centos Vbox 网络如下:

适配器1

 attached to : Host-only adapter  
 name : vboxnet0 

适配器 2

  attached to : NAT

然后我配置了 centos 网络设置如下:

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
TYPE=Ethernet
UUID=ff99b59d-162f-4838-baa7-c73384ab23f2
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
HWADDR=08:00:27:1D:BD:69
DEFROUTE=yes
NAME="System eth0"

并且:

 /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
TYPE=Ethernet
UUID=ff99b59d-162f-4838-baa7-c73384ab23f2
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
NAMEE="System eth1"

然后我重新启动 Vbox,当重新加载 Vbox 并输入 ifconfig 时,我得到:

eth0      Link encap:Ethernet  HWaddr 08:00:27:1D:BD:69  
          inet addr:192.168.56.102  Bcast:192.168.56.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe1d:bd69/64 Scope:Link

          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:315 errors:0 dropped:0 overruns:0 frame:0

当我 ping4.2.2.48.8.8.8收到以下信息时:

connect: Network is unreachable 

任何帮助都感激不尽!

谢谢!

答案1

我已设法通过将虚拟机(centos)适配器1设置为来解决此问题NAT并将适配器 2 连接至仅主机网络

然后我将虚拟盒网络(仅主机网络选项卡)配置为:

vboxnet0  
ipv4 address : 192.168.56.1
ipv4 network mask : 255.255.255.0

并启用DHCP服务器并进行如下配置:

server address : 192.168.56.100
server mask : 255.255.255.0
lower address bound : 192.168.56.101
upper address bound : 192.168.56.254

然后我启动了我的虚拟机并对其进行了如下配置:

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
HWADDR=08:00:27:1D:BD:69
DEFROUTE=yes
NAME="System eth0"
DNS1=8.8.8.8
DNS2=4.2.2.4

并且 :

 /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
NAMEE="System eth1"

重新启动机器后它就正常工作了。它可以使用我的主机网络
