CIDR is not supported. And if no_proxy variable is > than 1024 characters the variable is truncated un overcloud Reported by: raul.caballero https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.0/html/director_installation_and_usage/preparing-for-director-installation#annotations:91bba3ca-ea87-4279-908c-43d2a67b94d4
OSP16.0 was EOL on Nov 2, 2020 and for 16.1 we changed this section to a considerations section: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html/director_installation_and_usage/planning-your-undercloud#considerations-when-running-the-undercloud-with-a-proxy I'll leave this BZ open and move it to OSP16.1 because I'd like to find out more information about the 1024 character limit. That could be another limitation to add.
