## FIP auf VM funktioniert nicht, wenn Member eines OVN Load Balancers
70+
71+
Dies ist eine bekannte Einschränkung: Floating IPs (FIPs), die an eine VM angehängt sind, funktionieren nicht, wenn diese VM Member eines OVN Load Balancers ist.

## FIP on VM not working when member of ovn lb
69+
70+
This is a known limitation: Floating IPs (FIPs) attached to a VM will not work when that VM is a member of an OVN load balancer.
71+
72+
If SSH access to the VM is required, use a bastion host in the same subnet that has its own Floating IP.
