I have a server with one network card in it (eth1
). My server is assigned 5 public IP addresses and it is currently configured like this (/etc/network/interfaces
):
# The primary network interface
allow-hotplug eth1
iface eth1 inet static
address xxx.yyy.zzz.130
netmask 255.255.255.248
network xxx.yyy.zzz.128
broadcast xxx.yyy.zzz.135
gateway xxx.yyy.zzz.129
iface eth1:0 inet static
address xxx.yyy.zzz.131
netmask 255.255.255.248
iface eth1:1 inet static
address xxx.yyy.zzz.132
netmask 255.255.255.248
iface eth1:2 inet static
address xxx.yyy.zzz.133
netmask 255.255.255.248
iface eth1:3 inet static
address xxx.yyy.zzz.134
netmask 255.255.255.248
This is working perfectly, however I wanted to add a KVM virtual machine with a bridged connection with the public IP xxx.yyy.zzz.131
.
If I do this:
auto br0
iface br0 inet static
bridge-ports eth1
bridge_stp off
bridge_fd 0
bridge_maxwait 0
address xxx.yyy.zzz.131
netmask 255.255.255.248
Then only xxx.yyy.zzz.131
is accessible. None of the other IPs are.
If I change it to bridge-ports eth1:0
I get the error:
SIOCSIFFLAGS: Cannot assign requested address
RTNETLINK answers: File exists
Failed to bring up br0.
If I comment out the other sections about eth1:0
, in addition to the above error, I also get Ignoring unknown interface eth1:0=eth10.
at the beginning.
How do I add a bridged device if I only have one NIC and multiple IPs?
