Unsupported Firewall Rules

There are some firewall rules that may not supported on a cluster, but are currently open to networking traffic. It may be due to various of reasons, such as upgrading or downgrading cluster from a different version. If there existing such rules on a cluster, Instaclustr will display them as a table in the Firewall Rules setting page, and it is recommended you review these rules and if appropriate remove them to improve security. You can do this by clicking the button labelled “Remove all unsupported rules”. This will irrecoverably remove all the unsupported rules. 

Firewall rule type(s) which are unsupported

As Thrift API is deprecated in the Cassandra 4, Cassandra Thrift Rules will not be supported in our Cassandra 4 cluster. However, if upgrade a cluster from Cassandra 3, the old rules will still exist until the user remove them.
