## Advanced Instance Group config
### Adding allowed address pairs to ports
It is possible to make kOps provision and update the ports of the servers with allowed address pairs, which can be beneficial when needing to use for example VRRP for a custom loadbalancing solution.
To make use of this annotate an Instance Group configuration like so:
```yaml
kind: InstanceGroup
metadata:
annotations:
openstack.kops.io/allowedAddressPair/N: <IPAddress>(,<MACAddress>)
```
Where `N` can be an arbitrary identifier and the MACAddress is optional, for example:
```yaml
kind: InstanceGroup
metadata:
annotations:
openstack.kops.io/allowedAddressPair/0: 192.168.0.0/16
openstack.kops.io/allowedAddressPair/1: 10.123.0.0,12:34:56:78:90:AB
```
For more information about allowed address pairs refer to the [OpenStack Network API documentation](https://docs.openstack.org/api-ref/network/v2/#allowed-address-pairs).
## Next steps
Now that you have a working kOps cluster, read through the [recommendations for production setups guide](production.md) to learn more about how to configure kOps for production workloads.
