Mikrotik p2p security system

Hi,
I have Mikrotik RB750Gr3.

I connected security system with ethernet module but system can not connect to p2p server. The producent have a server and use p2p connection (more function from system example push notification in smartphone).
In router i config 2 vlan on trunk port and connect to swith. P2P system on Dahua Camera works but on Satel security not.
I can connect from application on smartphone to serurity system when i forward port and use ddns.,

I reset mikrotik to default configuration and use quickset to set dhcp wan, lan dhcp and nat and connect lan security system to mikrotik but it still not works.

Anyone have an idea what is wrong ? Why on default settings it not works?
When I use tp-link connect wan and security system it works.
