I am trying to open a port for my unity multiplayer game. I have a arris router, google wifi, and a windows 10 deveice. When setting up port forwarding on the arris setting page, it gives me an error “invalid IP address” How would I forward a port from the arris, to google wifi, to my windows 10 deveice, then finally to the internet so I can set up multiplayer across different networks. Anyone who can help even a little bit is greatly thanked. Also, would there be a faster way to open a port with the set up I have? Any tips are greatly appreciated.

Idea
I am tring to make two applications one on PC and one on android phones(maybe IOS). My desktop app is build on python and the phone app with .dart on flutter emul.
Basically the only thing I want is to pass a variable from my phone to a desktop and do something with it. Of course the 2 devices will be on the same home network.
Question
I have already tested HTTP requests and TCP connection and I got both of them to work. My problem is that I want this app to go online eventually and as things are the connection is made on my IPv4, that is different in every device.
How can I make the desktop server side to wait for a phone to connect on it and the phone to search and find the open IP and port and the name of the device?
I want to connect my flutter app to node server locally through my real device.I have seen many solution but still didn't get any clear picture.can anyone elaborate the steps to connect
you have two ways to do that:
1- if your mobile and computer - which contain (node.ja and database) - connected at same wifi, so, you should just go to CMD in your computer and type (ipconfig) and try to find the ipv4 for (wireless) or wifi, after that just in your mobile you can access the api by just replace (localhost) or (127.0.0.1) with your local ip which your found in cmd.....
or if you don't using wifi, you can just run your mobile hotspot, and connect your laptop with it by wifi, and also follow same steps as above...
Device must be able to connect to localhost:<port> but to make this happen connect your mobile to computer via usb or connect over same wifi connection.
After this hit chrome://inspect/#devices and port forward localhost: to so now you can easily connect to localhost:<port> on your mobile phone.

I’m broadly new to vuejs and socket.io and nodejs.
I wrote an single page application to communicate between a nodejs server (running on an Raspberry pi) and a Siemens S7-1500 PLC. Those ones are connected over ethernet and the raspi is getting me an wifi access point for control the PLC with a smartphone, tablet or Desktop.
I’m almost done, but I struggled at that point. I am using socket.io to send events to the client an back. For that i need to know the ip address of my sever inside my vuejs application with is bundled with webpack.
As I get to the point as I was trying to deploy my App onto the Rapberry Pi I didn't found a way to set the IP address dynamically inside my application.
Perhaps some of you guys could open my eyes and give me a Tipp for the solution.
How it's possible to send the IP Address to the client? My Application is running locally and there is no need to do not so.
In my mind it should be possible to send the server ip to the client.
Thank you for your Answers :)

You can use linux ifconfig command in order to get your IP from command line of the host application is hosted on. IP is not sth that you set on application level, but ussually is automatically asigned for the given host. So it depends on how your network is set up.
Look for sth like "How to give your Raspberry Pi a Static IP Address".
I've been having problems with a project of mine. I had a raspberry pi connected to webcams but I found that this was too much load for the RPI. This is why I decided to purchase and use an IP camera. The only problem though, is that the IP camera does not get wifi reception where the it should be placed but I have a powerful Directional antenna which I can attach to the RPI. I want the RPI to route internet traffic from the camera plugged into ethernet, over the wifi. I'm not one hundred percent sure how to do this but so far I have giving the wifi priority over the Ethernet and set up a dhcp server so that the camera gets an ip address.
In my current setup, when I am hard-wired into the Raspberry pi, I can connect to the camera (on 192.168.2.10) but outside, I can only connect to the web server which is also running on on the RPI. I'm not sure if the port forwarding of the camera works but I want to be able to access the webserver on 192.168.1.117 (this works) and I want to see the camera on 192.168.1.117:10 (this does not work). To try to do this, I followed this tutorial but I cant seem to get any results after finishing it.
Any help is greatly appreciated! thanks.
You may want to try UV4L with the mjpegstream driver. It turns your IP camera into a (virtual) Video device available on your RPi. An example is here (in step 3 pass the URL of your IP camera stream).
I am trying to connect 2 devices together using a datagram connection but so far it only works over localhost so I need to find the IP of the device to open the connection but I don't know how to do this. Can anyone help me?
