Hello all,
I should realize an IPsec VPN connection between a Fritz!Box7590 and a RUT2400 FW 1.14.1 for a customer. Unfortunately without success so far. The VPN connection to the Fritz!Box works correctly with an IPAD or when RUT2400 is connected to the IPAD without IPsec and the VPN client is running on it. Therefore, the problem must be in the settings of the RUT2400.
I have now tested many settings, unfortunately always the same. RUT2400 tries to connect to Fritzbox, but then aborts after the second attempt. Also i have checked the Post from Dec 15, 2020
I am using this IPsec settings:
Enable yes
Enable IPv6 no
Authentification type Pre-shared key
IKE version IKEv1 Mode Main
Use additional xauth authentification no
Type Tunnel
Local IP address/Subnet mask 192.168.1.0/24
Remote IP address/Subnet mask empty
On startup Start
My identifier IPsex ID / Groupname
Left firewall
Force encapsulation
Dead Peer Detection
Passthrough networks None
Remote VPN endpoint Serveradress.myfritz.net
Remote identifier empty
Right firewall
Allow WebUI access
Compatibility mode
Custom options
Phase1 : 3DES SHA1 MODP1024 Phase 2 3DES SHA1 MODP1024
Here the Logs from the sytem logfile:

Has someone already realized an IPsec connection to Fritz!Box and could send me the settings.
Thanks for your support!
