Use Softether VPN Server to connect to home LAN from remote location

RouterOS General
1

Hello everyone,
recently I got Mikrotik and I want to use it for connecting to my home LAN through Softether VPN server, that is available from internet.

This is my topology (simplified for only needed info)

I have set up L2TP client connection on Mikrotik to VPN Server through interface vpn-trixycz, Mikrotik is NOT at the edge of home LAN and ISP, but there is NAT to Modem.
Ping from Mikrotik to both networks works, I can ping to Remote devices and even to Server, but when I want to ping from Remote device to Server and reverse, the ping wont go through Mikrotik.

As I said, I am kinda new to Mikrotik, even though I read some documentations, tutorials and even forum discussions here, but I am not new to networking itself, I am familiar to cisco networking (which is not different in theory, but in practice there are few diferences).

Here are some prints of the configuration on Mikrotik:
