问题
I have a dedicated hosting with hetzner. Additionally i have bought a 6IP subnet.
My main IP is: 88.198.60.125 My main subnet is: 255.255.255.224
My additional IPs are 46.4.214.81 to 46.4.214.86
the internet access work on windows servers . but centos give me invalid host I cannot use bridged mode, since hetzner does not allow multiple MACs on same external ip, so I have to use routing mode. Here is my /etc/network/interfaces file for the host:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 88.198.60.125
netmask 255.255.255.255
pointopoint 88.198.60.97
gateway 88.198.60.97
post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
auto vmbr0
iface vmbr0 inet static
address 88.198.60.125
netmask 255.255.255.255
bridge_ports none
bridge_stp off
bridge_fd 0
bridge_maxwait 0
#subnet
up ip route add 46.4.214.80/29 dev vmbr0
up ip route add 46.4.214.81/29 dev vmbr0
up ip route add 46.4.214.82/29 dev vmbr0
up ip route add 46.4.214.83/29 dev vmbr0
up ip route add 46.4.214.84/29 dev vmbr0
up ip route add 46.4.214.85/29 dev vmbr0
up ip route add 46.4.214.86/29 dev vmbr0
up ip route add 46.4.214.87/29 dev vmbr0
and this my interfaces for vm
auto eth0
iface eth0 inet static
address 46.4.214.81
netmask 255.255.255.255
pointopoint 88.198.60.125
gateway 88.198.60.125

ok this how I solved the problem you need to specific The IPs you want to use them with WINDOWS SERVER using "up route add -host" and other IPs can be used directly with Linux using create container....installing Linux manual not worked with me this is my /etc/network/interfaces file
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 88.198.60.125
netmask 255.255.255.255
pointopoint 88.198.60.97
gateway 88.198.60.97
post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
auto vmbr0
iface vmbr0 inet static
address 88.198.60.125
netmask 255.255.255.255
bridge_ports none
bridge_stp off
bridge_fd 0
bridge_maxwait 0
#subnet ips used with windows server only
up route add -host 46.4.214.80 dev vmbr0
up route add -host 46.4.214.81 dev vmbr0
up route add -host 46.4.214.82 dev vmbr0
up route add -host 46.4.214.87 dev vmbr0
