You don’t need the port triggering at all and can delete that rule.
As you have set up the forwarding rule, your computer must be at the IP address that you are forwarding the port to, and that address must be on that network.
Since you have set it up as 122.100.xxx.xxx, it is almost certainly NOT on the network. The networks’ addresses are going to be in the 192.168.xxx.xxx or 10.xxx.xxx.xxx blocks – those chiefly reserved for private LANs. Your computer should also have an IP address in the appropriate block, and it must be a static address.
Your router has a WAN side, and a LAN side, and it does network address translations between the two. From the computer, the router is its gateway to other networks, but it cannot see them. All it can see is the LAN, at one of those two reserved blocks.
The 122.100.xxx.xxx address is WAN side. You don’t mess with that, it’s assigned by your provider.
Find the LAN-side address for your router. This will be the address you use to configure it. Typically, it will be something like 192.168.1.1
You willl typically be using a netmask of 255.255.255.0 Put that together with the router’s base address and all of the devices on your LAN will have addresses that start with 192.168.1 and the final number of the quad will be between 0 and 255. We generally don’t use the 0 address. That still leaves you with 255 numbers to play with. Very few people have 255 devices that need network connections.
Your router itself is taking up the first one. You can set your computer up to take the last one, that’s 192.168.2.255
In your network settings, adapter properties, Internet Protocol Version 4 properties, uncheck “Obtain an IP address automatically”, and instead fill in your computer’s address, your netmask, and your gateway address. For now use the gateway address for your first DNS server and leave the second blank.
Edit your router’s rule to point to your computer’s IP address as you’ve just set it up. Now your listen port should be open.
