Hello everyone,
i try to build a VPN with L2TP IPsec for windows and linux clients. But on phase 2 of the connection it failed.
I tried the connection from windows 10 client
Here is the log:
respond new phase 1 (Identity Protection): 2a00:…[500]<=>2a00:…[500]
ISAKMP-SA established 2a00:…[500]-2a00:…[500] spi:201492…:5a147b68…
2a00:… failed to pre-process ph2 packet.
Could someone give me a hint, what the problem can be?
Thanks a lot
