| 10 | 1 | Tobias Brunner | h2. Behavior |
| 11 | 1 | Tobias Brunner | |
| 12 | 1 | Tobias Brunner | When an IKEv2 client requests a virtual IP address via a configuration payload, the plugin allows the daemon to forward this request to a DHCP server. By default the plugin uses broadcasts, but a designated DHCP server can be configured in [[StrongswanConf|strongswan.conf]]. |
| 13 | 1 | Tobias Brunner | |
| 14 | 1 | Tobias Brunner | DNS/WINS server information is additionally served to clients if the DHCP server provides such information. |
| 15 | 1 | Tobias Brunner | |
| 16 | 1 | Tobias Brunner | The MAC address used in the DHCP request is either randomly generated or can optionally be based on the IKEv2 identity of the client. |
| 17 | 1 | Tobias Brunner | |
| 18 | 1 | Tobias Brunner | In combination with the [[FARPPlugin|farp plugin]] this plugin lets a road-warrior act as a client on the local LAN of the responder. |
