ikedv2 - Erfahrungen mit Verbindungen zwischen OPNsense & OpenBSD
« on: October 01, 2020, 10:34:13 am »
Habe dieses Thema auch schon in einem OpenBSD-Forum aufgemacht aber leider ohne Erfolg, da die Ratschläge und Empfehlungen leider nicht zum Erfolg führten.

Ich verzichte mal auf einen kompletter Übertrag der Informationen und würde an dieser Stelle bloß eine Verlinkung auf das andere Forum setzen, da hier schon alle Informationen zusammengetragen wurden - wenn es anders gewollt ist, einfach schreiben bzw. wenn weitere Informationen erforderlich sind!

looking for peer configs matching 192.168.1.1[%any]...192.168.1.2[OpenBSD]

Die OpenBSD Kiste meldet sich mit ID OpenBSD und nicht mit der IP.
Auf einer Seite bitte ändern.

Habe versucht es zu ändern, aber auf der OpenBSD-Seite parsed er meine Konfig dann leider nicht. Wo muss ich es bei der OPNsense ändern?

Kann es sein, dass ich vielleicht ein Problem mit NAT habe?
