# Reconfigure WireGuard

The `SaveConfig = true` directive causes the `wg-quick` service to overwrite the config file, so modifications to the config should either be made using the `wg` or `ip` commands directly, or by shutting down the `wg-quick` service before making any edits to the config file.

## See Current Config
to see WireGuard's status and configuration, run:
```
sudo wg show
```
to see what ip the `wg0` interface is configured with, run:
```
ip addr show wg0
```

## Change Port
to change what port WireGuard listens on for interface `wg0`, run:
```
sudo wg set wg0 listen-port ${new_port:?}
```

## Change IP
to change what IP the interface `wg0` has, run:
```
ip addr del ${old_ip:?}/24 dev wg0
ip addr add ${new_ip:?}/24 dev wg0
```
