L2TP Problem with iOS & Windows but good with android

Hi
I have a router with v 6.49 packages.
There is only one interface that have fixed public IP on dhcp client.
I ran L2TP server and did all the config but I can’t connect windows and iOS clients to it.
All of the clients are behind NAT and connect through their local internet in multiple points.
I have read the relevant topics but they were not my case.
IPSec logs are attached.
Thanks in advance.
