如何从本地网络中连接的设备获取数据到我的应用程序

Question

I am trying to get data from a device which is connected in the local network.

The device listens to 192.168.1.2:10000 For example we can call the function getItems() on the windows computer in the network and we get all the items.

Now I want to do this in my cloud application (php). So I want that example.com/getItems get the items from the device.

I am a noob at networking, so I hope someone can give some advice how to handle this.

Answer 1

at least you need to open your local firewall and expose the Port 10000 and NAT it to you local 192.168.1.2:10000 to the public internet.

If there are no further IPv6 restrictions and you have a static IPv6 address you can reach that it from the cloud php. If you have a typical private internet access, consider to use a dynDNS or similar service to reach you changing IP by a static FQDN.
