You give no description re symptoms why it is not working!!!
It seems you are making ssinf some attributes in your port forwarding rule, name destination address and or in interface / list

I made a mistake, why can not dst 1723 port to other IP, bcoz when you want to port map 1723 port, you must enable pptp port in firewall-service ports and leave this parameter blank.
