 * Create a `NodeNetworkConfigurationPolicy` (NNCP) CR and define a customized `br-ex` bridge network configuration. Depending on your needs, ensure that you set a masquerade IP for either the `ipv4.address.ip`, `ipv6.address.ip`, or both parameters. A masquerade IP address must match an in-use IP address block.

+[IMPORTANT]
+====
+As a post-installation task, you can configure most parameters for a customized `br-ex` bridge that you defined in an existing NNCP CR, except for the IP address.
