# nova-network change multi-host T to F of used network

Hi!

When I set up Openstack, I used the same commands as in the manual stood. I used the fixed network for direct access to the internet for my VMs. in the shell: nova network-create public --bridge br100 --multi-host T --fixed ....

I didnt know that we would still use the same Hoster and expand it.

Now the pain. I added a second Compute Node with a sperate AVZ and its on fixed network. But everytime i start a new VM, the First assigned IP, is from the Subnet of a different node ..

nova network-create public --bridge br100 --multi-host F --fixed-range-v4 148.251.216.144/28

Now my new Compute-Node has 2 bridges. The 1st is the one, that should be used by the old one. The second bridge is the one that should be assigned and used, not the first.
