[App_rpt-users] Firewalls and outbound connections

[Peter Elke]

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?
