# Interfaces configuration

The interfaces configuration lists all interfaces for your firewall and also
tells which zone they are attached to.

Example interface configuration for attaching the network interface 
```eth0``` to the ```lan``` zone. The interface is configured via DHCP, so the
dhcp-client option is also being set:

```yaml
---
eth0:
  zone: lan
  options:
    dhcp-client: true
```
