[App_rpt-users] Private network

Hi, we're planning to setup an emergency network of voting repeaters and simplex nodes, some of them will be connected directly using private wireless network and some of them by internet. Those of them which connected using wireless have to see each other in absence of internet connection and must be able to connect to those of them which connected over internet, when the internet connection is available. Would someone please to give step by step instructions of what do i need to do? Thanks!
