_Installation details_  
#ScyllaDB version: 6.2.3  
#Cluster size: 3  
#os (RHEL/CentOS/Ubuntu/AWS AMI): Debian

I want port 9042 to listen on all IP addresses.  
I am trying to configure networking as described in scylla.yaml:  
# If you leave broadcast\_address (below) empty, then setting listen\_address  
# to 0.0.0.0 is wrong as other nodes will not know how to reach this node.  
# If you set broadcast\_address, then you can set listen\_address to 0.0.0.0.

For example:  
listen\_address: 0.0.0.0  
broadcast\_address: 10.10.10.10

After I do so, port 9042 is not brought up and there is nothing in debug logs to say why.

Please try:

```auto
listen_address: 0.0.0.0
broadcast_address: 10.10.10.10
rpc_address: 0.0.0.0
broadcast_rpc_address: 10.10.10.10

```

Check if port 9042 is being listened on by any other service.

```auto
ss -tnlp | grep 9042

```
