Log into your router. Click on the Advanced tab and look at IP Address listed under Internet Port. Reply with the first half of the address.
As to checking port forwarding, there needs to be a service running on the port you opened. What service are you trying to run?

Do you have a service running on 192.168.1.19 that is listening to port 1604?
Does your R7800 have a public IP address (i.e. 95.143.x.x) on its Internet/WAN port?
P.S. For privacy, you shouldn't share your public IP address. It's visible in one of your pictures.

Glad you got it working. I wish those port testing services would make it more clear that they are end-to-end tests. If there's nothing at your end to respond to their test, then it can appear to many that the port is not being forwarded when in fact it is. Note: Some port testing services can actually listen to the port and respond to requests, provided that you initiate the test on the device that you are port forwarding towards.
It's important to understand that there is a subtle but important distinction when a testing service reports that a port is "closed" vs "didn't respond". "Closed" means the other end actively rejected the connection request. This usually means that the port is being forwarded. "Didn't respond" usually means that the router silently blocked the request because the port is not being forwarded.
