How to reach other devices on the ESP32 WiFi Network

[bwjohns4]

Is it possible using this library to access other IP addresses on the ESP32 WiFi Network Interface? The new interface that is setup by this library is only on the VPN network, right? If packets are sent to the ESP32 with a different destination IP address from the VPN interface, would the ESP32 already know which interface to forward them out of, or would that need to be built separately? If that needs to be done separately, would you be able to point me in a direction to get some insight on how to do this?

This was a little bit tricky on the ESP32. I had to copy over the ideas from the Arduino ESP8266 version and build the add a reading topic functions to add reading topics to subscribe to other IP addresses. You also need to enable NAPT similar to the way it was done for ESP8266. I plan to submit a PR with my changes to allow this.
