VPN PPTP server + clients with same LAN IPs

RouterOS Beginner Basics
1

Hello,

I have several TP-Link-and who are behind the ADSL. Routers have the same configuration: wan ip 192.168.1.2 and lan ip 192.168.2.1 with redirected ports to PC: 192.168.2.2
I set one Routerbord for VPN PPTP server. My problem is that when you hang TP-Linkovete to VPN-a, port forwarding them does not work.
Here export of mikrotika:

/ip pool
add name=POOL_VPN ranges=192.168.2.1-192.168.2.254
/ppp profile
add local-address=192.168.2.1 name=VPN remote-address=POOL_VPN
/interface pptp-server server
set enabled=yes
/ppp secret
add name=TP-Link1 password=TP-Link1 profile=VPN remote-address=\
    192.168.2.11
add name=TP-Link2 password=TP-Link2 profile=VPN remote-address=\
    192.168.2.12
add name=TP-Linkn password=TP-Linkn profile=VPN remote-address=\
    192.168.2.1n

In torch all connections from any TP-Link come with 192.168.1.2

Have you configure firewall rules in the Mikrotik?
So yes
PPTP traffic uses TCP port 1723 and IP protocol GRE (Generic Routing Encapsulation, IP protocol ID 47), as assigned by the Internet Assigned Numbers Authority (IANA). PPTP can be used with most firewalls and routers by enabling traffic destined for TCP port 1723 and protocol 47 traffic to be routed through the firewall or router.
