I've got a AMS Pow-K Power Measure ioT Device. Sadly its out of Range from my WiFi. So instead of using a WiFi Repeater i tought i'd route this device over the WiFi from my Landlord.
Works fine, device is connected to his WiFi, i can access it via Smartphone.
I've even connected my Router as a Client to the WiFi.
But here comes the issue.... both use the same Subnet.
My Router IP in his Network: IPv4: 192.168.1.120/24 on my own network it's 192.168.1.1
The device i want to connect to is on 192.168.1.118 with Mac D4:F9:8D:6E:86:96
Is it possible to keep the same Subnet? Because right now i can't connect to the device from my own Lan.
How do i have to configure the Firewall that ALL Access will be blocked except Web (Port 80) and MQTT (port 1883) for this device?
For trial&error i set the newly created interface "wwan" to the same firewall zone as "lan". But i still can't connect to the device... is it a subnet issue?
