Site to Site PPTP - Another VPN Client can not ping networks

Hi all,

I am new in this field, so maybe you can help me. I have the following configuration:

Site A - mikrotik router, local network: 192.168.2.0/24 (static public IP Address: 86.xxx.xxx.xxx)
Site B - mikrotik router, local network: 192.168.3.0/24 (dynamic public IP Address)

I created a VPN server on Site A and VPN Client on Site B. From computers connected to Site A lan I can ping computers connected to Site B lan. But if I connect to Site A from another computer, using VPN, I can not ping Site B computers, only Site A computers.

Please see below both routers configuration:
Site A configuration:
