Connect to ownCloud from another network - Port Forward


Hello, i has been using ownCloud on my raspberry pi 3 for a week, but now i need to be able to connect with out been on the same network, i read something online but I could not find much other that open the port forward 443. But ther is the problem, my router don't have the "port forward" option, the only things that look like that are:

Port Mapping

and the other one is IPv4 Forwarding

Which one is the right one? What i should use?

Thank to all


There is the IPv4 Forwarding
