Port forwarding software (service) for Windows

netsh interface portproxy add v4tov4 5118 127.0.0.1 8182
netsh interface portproxy add v6tov6 5118 ::1 8182

Note that the service will see the user as connecting from "localhost", which may be undesirable for logging purposes.

"IP Helper" service must be enabled and running !

You can also try:

netsh routing ip nat add portmapping "LAN NAME" tcp 0.0.0.0 5118 192.168.0.3 8182

Where 192.168.0.3 is the target server ip.

If port 5118 comes from internet this port has to be open in your firewall/router.
