networking – Enable SSH on my computer from the outside via port forwarding

I can ssh on my computer1 from my computer2 on my local network, using my local IP address:

ssh user@192.168.1.5

However, I want to use SSH from outside my home, using my public IP address:

ssh user@113.174.34.171

I have access to the configuration of my router (ZTE F600W) but I obviously can not perform the port transfer correctly.

I've tried different things and restart the router 10 times already.

The firewall on my computer is disabled. Is there anything else that I can possibly check?
