How to set up port forwarding

Background: Port forwarding is used to allow the router to forward traffic from a public IP to another interface (typically LAN). This allows a user to reach a device on the router through the public web. In addition, if multiple devices use the same port, it allows the router to assign a different source port (public port), so port 50 and 60 can be forwarded to port 80 on two different devices.

In this experiment, IR305 is directly
connected to the PC, and IR305's downlink device is IR302. The specific
connection is as follows.

4.     Via
the IP address of IR305: Service Port,, you can access IR302 from other
devices. For example 10.5.27.196:8001. The result is as follows.

I've been searching for a day or so: how do you reach the modem when it's ONLY on cell, no WAN?
