Hi,
You need to configure destination NAT on router to achieve the goal.
For example, 1.1.1.1 is your public ip address, Any Internet user will access the 1.1.1.1 and by using destination NAT router will translate 1.1.1.1 to your private IP address 192.168.1.119.
#ip nat inside source static <Inside local IP address> <Inside global IP address>
You also can forward/specific specific ports
For Example you only want to forward/open port 443 for IP 192.168.1.119
#ip nat inside source static tcp <Inside local IP address> 443 <Inside global IP address> 443
