## IP Blacklist/Whitelist Settings

**Whitelist:** Used for inter-service calls. The IP address of the proxy forwarding server must be added to ensure interface calls do not fail. The system defaults to `192.168.x.x` addresses and the main node's IP prefix.

For elastic public cloud IPs where setting individual addresses can be cumbersome, you can alternatively configure the admin credentials via a configuration file:

```
pxy.security.admin-key=603284317954637824
pxy.security.admin-secret=c8333614aca34ebcb6fbaccc31196d37
```

**Blacklist:** By default, external calls to interfaces are permitted. Adding an IP address to the blacklist will result in the inability to make calls.

You can set the blacklist by providing complete IP addresses or using IP prefix matching.
