DSTNAT Cannot access from out side router1 to local router2

I have 2 Mikrotiks device that connected by IPIP tunnel and i can ping all my local Ip from both side. (IPIP tunnel is connected)
From : 192.168.1.xxx can ping all range 192.168.2.xxx and also from 192.168.2.xxx can ping 192.168.1.xxx
Now the problem is i want to connect by DSTNAT router 1 from out side to local IP of router 2 . that mean
Router 1:
chain=dstnat action=dst-nat to-addresses=192.168.2.200 to-ports=5900
protocol=tcp dst-address=185.11.146.128 in-interface=PPPOE-Client-E2-128
dst-port=6060 log=no log-prefix=“”

but it will not connect to local range router 2

Router 1 :
WAN Route 1: 185.11.146.128
IP range Router 1 : 192.168.1.0/24

Router 2 :
IP Range Router 2 : 192.168.2.0/24


When run 185.11.146.128:6060 it must load but does not work .
