I have a centos 6.3 server with kvm installed. The server has 4 external ips and one NIC.
176.9.xxx.xx1
176.9.xxx.xx2
176.9.xxx.xx3
176.9.xxx.xx4
I use the following configuration
ifcfg-eth0 as slave to ifcfg-br0
the configuration in ifcfg-eth0 is
DEVICE=eth0
ONBOOT=yes
BRIDGE=br0
HWADDR=14:da:e9:b3:8b:99
and in the ifcfg-br0
DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
BROADCAST=176.9.xxx.xxx
IPADDR=176.9.xxx.xx1
NETMASK=255.255.255.0
SCOPE="peer 176.9.xxx.xxx"
and I have 3 more aliases for br0 , br0:1 to get the trafic from the second external ip
DEVICE=br0:1
IPADDR=176.9.xxx.xx2
NETMASK=255.255.255.248
ONBOOT=yes
br0:2 to get the trafic from the third external ip
DEVICE=br0:1
IPADDR=176.9.xxx.xx3
NETMASK=255.255.255.248
ONBOOT=yes
br0:3 to get the trafic from the second external ip
DEVICE=br0:1
IPADDR=176.9.xxx.xx4
NETMASK=255.255.255.248
ONBOOT=yes
The above settings work fine and I recieve the trafic from all the external ips.
My problem is that I want to pass the trafic from external ip to specific virtual guest on my server. ie trafic that comes from
176.9.xxx.xxx2 must pass to virtual machine 1
176.9.xxx.xxx3 must pass to virtual machine 2
176.9.xxx.xxx4 must pass to virtual machine 3
Can you please help me how to achieve this ? What are the settings on the host and what should I do to the guests.
Thank you in advance
