For port forwarding I prefer you to use portmap.io. Configuration steps are given below:
Step 1:
Go to your browser and search for portmap.io then simply register your account using temp mail or any other temporary email service provider .
Step 2:
Go to configuration and create new configuration file with tcp protocol and download that file in your PC or VM or RDP.
Step 3:
Download OpenVpn and import that file there or you can simply import it by double click on the file.
Step 4:
Go to mapping rules and there create a new rule with tcp protocol (Don't put https) and in host name use portmap.io not portmap.host then simply copy your user name and port and configur your RAT.
