Einer ne Idee warum der hier irgendwie was mit Zerts machen will? Soll er nicht!
-
Paar Sachen:
- Wieso respond-only wenn du bei Peer Identifier "MyAddress" hast, das ergibt keinen Sinn. Hat einer dynamische IPs?
- Wieso IKE auto? Wenn du beide Seiten kontrollierst bitte gleich v2.
- Mach den Quatsch Blowfish etc. raus, AES256, SHA256 .. das reicht, nicht zu knacken.
- PFS in P2 muss mind. 5 sein, eigentlich 14 .. ansonsten kannst du die Daten auch plain schicken (jedenfalls wenn du Angst vor Behörden hast)
- automatically ping host und "Start Immediate" beissen sich in manchen Kombinationen, z.B. Sophos-OPNsense

Moin!
Yep zu Hause habe ich ne Dynamische IP - Noch!
Wegen v2 habe ich geändert
PFS habe ich nun auch geändert sowie auch Blowfish etc. rausgeschmissen. Habe jetzt nur noch AES256, SHA256 und PFS Group14)
Disable MOBIKE war die Lösung nach dem ich das auf beiden Seiten gemacht habe, nimmt er keine Zerts mehr.

Also passt alles? :)
