I have situation for test opennebula.

- OpenNebula with white static IP (for example 180.0.0.2)
- Mikrotik with another IP (for example 180.0.0.3) and his local IP 192.168.88.1
- KVM node in local network with IP 192.168.88.2  
My task was to create another local network in OpenNebula with the help of router os

In the begining I create 2 bridge in the KVM node:  
the first one for connecting VM to local network  
the second one for connecting virtual router to 192.168.88.0/24 network

We create virtual router with 2 interfaces: local and internet.  
At first i edited local interface (gave pool of local addreses and turned on dhcp )  
Than wrote nat rule masquarade from ON local network to internet interface.  
As i remeber in internet interface i set up only IP address
