I Searched a lot about how to make an l2tp or pptp vpn app using react-native but i didn't find anything anyone has solution?
Example projects:
You can fork them on github and make the changes you want to.
[EDIT]
You can use react-native-ip-sec-vpn now!
Use it like as follow:
import {prepare, connect} from "react-native-ip-sec-vpn";
...
useEffect(() => {
prepare();
}); /// or use componentDidmount in case of a class component
...
connect(address, username, password)
