|
|---|---|---|---|
| Name: | wan0 | The prefix wanx should be kept at all costs. The prefix wan is used to identify this interface as a WAN interface and, possibly, displayed or hidden in selection menus. | |
| Interface: | wan0 | The physical interface to which the PPPoE interface is to be bound. | |
| MTU: | 1492 | Gibt die maximale Paketgröße an. Bei Ethernet-Verbindungen ist der Standardwert 1500 Byte. Da PPPoE allerdings 8 Byte für Verbindungsinformationen benötigt, liegt der Standardwert bei 1492 Byte. | |
| Redial: | Off | Wenn eine Uhrzeit ausgewählt ist, wird zu dieser Zeit die Verbindung erneut aufgebaut, nachdem sie vorher einmal getrennt wurde. | |
| Link Control Protocol: | On | Aktiviert das Link-Control-Protocol (LCP) | |
| LCP Echo Intervall: | 5 Seconds | Legt den Zeitraum zwischen den Test-Signalen fest, die prüfen, ob die PPPoE-Verbindung noch steht | |
| LCP Echo Versuche: | 3 | Legt die Anzahl an Test-Signalen fest, die gesendet werden, wenn keine Antwort-Signale kommen. Wenn bei allen Versuchen kein Antwort-Signal kam, wird die Verbindung getrennt | |
| Dial-on-Demand: | Seconds | Legt die Zeit fest, die nach dem letzten Datenpaket vergehen muss, bevor die Verbindung getrennt wird. So besteht die Verbindung nur, wenn sie auch benötigt wird | |
| IPv6: | Off | Aktiviert IPv6 für diese PPPoE-Verbindung | |
| IPv6 Prefix Delegation: | Off | Aktiviert die IPv6 Prefix Delegation für diese PPPoE-Verbindung | |

Zones Zones | |||
| Zones: | »external »firewall-external »external_v6 etc. | The wizard automatically takes over all zones of the physical interface. The zones are no longer needed there. The physical interface (here: A0) is only used for communication between the firewall and the modem. However, it is possible to manually select previously created zones in the click box and remove existing ones. |

Fallback Fallback notempty
v07.2026 | |||
| Fallback interface: | wan1 | Interface that stands in for the main interface in the case of a malfunction. The absence of malfunctions is verified by ping-checking an IP. Further notes on the configuration of a fallback can be found in a separate Wiki article. |
![]() Fallback settings
|
| Ping-check IP: | »203.0.2.203 »192.0.2.192 |
Host(s) to which the ping check is to be performed. This can also be a host in the internal network if necessary. This may also be a host in the internal network. If a ping check host does not respond, the subsequent IP address is tried immediately. If none of the ping check hosts responds, this is considered a failed attempt and checked again after the ping check interval. | |
| Ping-check Intervall: | 5 Seconds | Period between ping attempts | |
| Ping-check Threshold: | 4 | Number of failed ping attempts before switching to the fallback interface. | |
