I've been using vncserver and version since at least Fedora Core 3, and 
currently have it running on Fedora 20 in my classroom. Here are the results 
I see in the firewall setup I have and I start it via rc.local, but have used the 
systemctl option with 16, 17, and 18 in the past, but ran into some issue with 
20.

Contents of /etc/firewalld/services/vnc-server.xml

<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>Virtual Network Computing Server (VNC)</short>
  <description>A VNC server provides an external accessible X session. 
Enable this option if you plan to provide a VNC server with direct access. The 
access will be possible for displays :0 to :3. If you plan to provide access with 
SSH, do not open this option and use the via option of the VNC 
viewer.</description>
  <port protocol="tcp" port="5900-5979"/>
</service>

Contents of /etc/firewalld/zones/public.xml

<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Public</short>
  <description>For use in public areas. You do not trust the other computers 
on networks to not harm your computer. Only selected incoming connections 
are accepted.</description>
  <service name="ftp"/>
  <service name="mdns"/>
  <service name="vnc-server"/>
  <service name="dhcpv6-client"/>
  <service name="ssh"/>
  <port protocol="tcp" port="9000-9001"/>
  <port protocol="tcp" port="5979"/>
  <port protocol="udp" port="9000-9001"/>
</zone>


I start up the vncserver via /etc/rc.d/rc.local
USERNAME is my ID, and here I use port :79 which is 5979

runuser -l USERNAME -c 'vncserver :79 -geometry 1280x1024'

In the past I had used the systemctl option to set it up, but it was more 
complex, and with Fedora 20 it wouldn't restart like it would in previous 
version, so this is what I have found works best for me.

I have also used stunnel in the past on other machines that were accessed 
from outside to do the secure connections.  The ports 9000-9001 are for 
udpcast.
