Allocating and Associating a Floating IP (Freiburg Region)

For assigning a Floating IP is a configuration as illustrated below (or something similar) required. Here is a summary:

  1. Allocate a Floating IP to the project
    1. Network -> Floating IPs
    2. Allocate IP to Project
      • Choose the public network/pool
  2. Virtual network creating
    1. Network -> Networks
    2. Create Network
      • Network Name vergeben
    3. Next and the slider Subnet is presented

      • Set Network Addresse (z. B. 10.10.1.0/24)
      • Set Gateway IP (z. B. 10.10.1.254)
    4. Next and the slider Subnetz Details is presented

    3. Choose router in the view -> Interfaces -> Add Interface
      • Set Subnet to the network from step 2
    4. Submit

Afterward, create a VM as follows:

  1. Compute -> Instances -> Launch Instance

    2. Launch Instance
  2. In the view of the instance -> Associate Floating IP
    1. Set IP Address from step 1
