running the project throwing error

[saimanohar1999]

Hi,

I just downloaded your repo: https://github.com/martin-ger/lwip_nat_arduino

now I tried to run the WiFiNatRouter.ino

I want to implement something like a Wi-Fi repeater.

But when I run I am getting the following error. please note hwne I am running wifinatrouter.ino it asked me that the code should be inside the folder.
My setup looks like this

error:

C:\Users\I71839\Downloads\lwip_nat_arduino-master\lwip_nat_arduino-master\WiFiNatRouter\WiFiNatRouter.ino:5:10: fatal error: lwip/app/dhcpserver.h: No such file or directory
