Problem in Port Forwarding

I have Mikrotik RB951G-2HnD
I make the quick configuration for the router to input the internet using my PPPOE Client and to get it out for normal dhcp pool 192.168.1.0/24 and im trying to make port forwarding to one of the internal IPs but its not work

I need to forward the port number 5555 to the ip : 192.168.1.11 : 4455

Use this command:

/ip firewall nat add chain=dstnat dst-address="public address" protocol=tcp dst-port=5555 action=dst-nat to-addresses=192.168.1.11 to-ports=4455

Remember: “public address” is your router public ip address like 1.1.1.1
