Hello,
Firstly, could you please tell me if there is a reason why you are using a legacy firmware version? If possible, it would be great if you could update to the latest firmware version.
Regarding the configuration, it is hard to say why the tunnel does not established from these screenshots. Would it be possible for you to download a troubleshoot file and attach it to your question? Troubleshoot file can be downloaded from System -> Administration -> Troubleshoot. You can attach the files by editing your question. The attached files are only visible to Teltonika Moderators.
Before you download a file, make sure to allow some time for the RUT240 to try and establish an IPSec tunnel.
Addionally, could you please show the IPSec configuration on the FritzBox?
Kind Regards,
Andzej
