How to PROPERLY route a subnet to the VMs without wasting an IP?

Hello,

I have a main server IP and a /29 subnet assigned by the DataCenter.
Their suggested configuration says that I must create a bridge with one usable IP from the subnet:

>>
# for a subnet
auto vmbr1
iface vmbr1 inet static
address <A usable IP address from the additional subnet>
netmask <Netmask of the additional subnet>
bridge_ports none
bridge_stp off
bridge_fd 0
>>

Is there another way to do it without wasting one IP so I can use all 6 IPs from the /29 subnet :confused:
