I’m not particularly networking savvy, in fact I’m at the opposite end of networking familiarity. I’ve contacted Wayne a few times to ask that the K4 remote solution (whether K4/K4-0 or VK4 software) follow the KISS principle and make connectivity simple enough for someone like me. I’m hoping I won’t have to try to figure out tunneling, setting up a VPN or any of the other alphabet soup solutions that quickly turn into blah blah blah for me.
