[Gelöst] IPsec IKEv2 & Android

[guest16192]

Hallo zusammen,

wie im Titel schon zu erahnen ist, möchte ich IPsec mit IKEv2 einrichten, damit ich mit meinem Android Smartphone (Android 7) mich verbinden kann.

Habe im Forum bereits diesen Eintrag gefunden OpnSense:https://forum.opnsense.org/index.php?topic=4324.msg16350#msg16350 der auf PFSense:https://forum.pfsense.org/index.php?topic=106433.0 verweist.

Leider wird im OpnSense nur auf https://docs.opnsense.org/manual/how-tos/ipsec-road.html, welcher nur für IKEv1 ausgelegt ist(?)


Großteil des Aufbaus scheint bereits zu funktionieren, aber irgendwo verschluckt er sich.

Edit:
Ok, wenn man die falsche Authentication method wählt ist klar dass nichts geht. Richte ausgewählt und es geht wie es soll
