We are evolving to offer special low tarrif to smartphone and tablet users via secured vpn (openvpn). For the vpn access concentrator we plan to go with pritunl - https://pritunl.com - which support radius authentication https://docs.pritunl.com/docs/two-step-authentication.
The challenge is to integrate customers and their service in splynx billing and radius with pritunl as network access server (nas).
Has there been such a use request? Is the integration feasible?
