Hi All, This may be an obvious and I am just not "getting it" but here it goes. We are setting up an 440 & 902Mhz Emergency communications system with a repeater node in a suite case sized Pelican box. In the box is 902/927Mhz Repeater, 12volt Linux PC, WiFi Card + FOB. The idea is that we could set this up (as an example) at a hotel near a wildfire command post. The local operator would make an always on outbound connection to a node used as an "inbound hub" via the hotel "guest wifi" or Ethernet. My question is can a node create an outbound connection without any major firewall modifications? If not my other option will be to have linux create a SSL VPN connection to somewhere "outside" and VoIP UDP openly from there. Any thoughts on this? Other ideas? Pete/WI6H
