Im not sure if anyone has and idea or if its possible but!!!

I have a controller that is a static ip address of 192.168.16.254 and an app on my phone that connects directly to it! But my issue is my phone disconnects from it and connects to my main wifi because of no internet.

I was thinking if i could source nat the deivce or something

I would like to either have my phone on my 172.27.1.x subnet (MAIN NETWORK) and have it route to the 192.168.16.x network but my issue is i cant add a default gateway on the controller so i dont see how i can route it? The app is programed to look for that address!!!!

My other thought was to create another network for the controller and phone and set my phone to use the router as its default gateway so it can connect to the controller on the same subnet but the phone would have default gateway to get to the ineternet. I would prefer the fist option so i can route it over the internet!


Hope this make some sense!

what does the device if you use dhcp ? (you can make this static)

does it then accept a default gateway?

Hi,

I think it will be much more easy for you if you give the static IP to controller from the same Subnet as your phone is getting for internet access. You will have a local access to you controller without needing any routable accesspoint which forward you data to the controller and don't nat it for that address.

I was able to figure it out with source nat and some routing its working!!
