# iocage option defaultrouter

The iocage option ``defaultrouter`` is needed if the jails are provided with the
DHCP on the bridge. In this case, the defaultrouter for the jails is the address
of the bridge. For example,

```yaml
properties:
  bpf: 1
  dhcp: 1
  vnet: 1
  notes: "vmm={{ inventory_hostname }}"
  defaultrouter: 10.10.99.1
```

pf must provide NAT and redirection. See example 440.

This is the difference between the example 203 and this example. In the example
203, DHCP is central to the local network. NAT is simple and redirection is not
needed. See the example 370.
