# AP to PPPoS example ## Overview This example focuses on the networking part, enables forwarding packets between network interfaces. It creates a WiFi soft AP, which uses NAT to forward packets to and from the PPP network interface. ### Specific network DCE Note, that this example could use of a minimal Network DCE, defined in the `network_dce.cpp` file. Please set `EXAMPLE_USE_MINIMAL_DCE` to `y` in order to demonstrate this functionality. By default, this example simply connects to the PPP server using a supported device with C-API modem interface. This example however, doesn't rely on sending specific AT commands, just the bare minimum to setup the cellular network. Thus, if the `EXAMPLE_USE_MINIMAL_DCE` option is enabled, we directly inherit from the `ModuleIf` and implement only the basic commands. Also, to demonstrate the dce_factory functionality, a new `NetDCE_Factory` is implemented for creating the network module and the DCE. ### Supported IDF versions This example is only supported from `v4.2`, since is uses NAPT feature.
