In gnome settings I can enable sharing and screen sharing but other than the ui gives me I don't have any control over the service.
I can't forward ports on the router because I'm using Internet provided by the landlord.
Trying to change settings through gconf does not seem to do anything:
[me@localhost]$ gsettings set org.gnome.Vino alternative-port 2000
[me@localhost]$ gsettings set org.gnome.Vino use-alternative-port true
[me@localhost]$ gsettings list-recursively org.gnome.Vino
org.gnome.Vino notify-on-connect true
org.gnome.Vino alternative-port uint16 2000
org.gnome.Vino disable-background false
org.gnome.Vino use-alternative-port true
org.gnome.Vino icon-visibility 'client'
org.gnome.Vino use-upnp true
org.gnome.Vino view-only true
org.gnome.Vino prompt-enabled true
org.gnome.Vino disable-xdamage false
org.gnome.Vino authentication-methods ['none']
org.gnome.Vino network-interface ''
org.gnome.Vino require-encryption false
org.gnome.Vino mailto ''
org.gnome.Vino lock-screen-on-disconnect false
[me@localhost]$ lsof -Pnl +M -i4 | grep vino
vino-serv 10862 1000 13u IPv4 179445 0t0 TCP *:5900 (LISTEN)
Note that after changing the settings I pretended I was on Windows and tried rebooting to see if it had any affect. Then started sharing through the UI but it still listens to the same port.
Not sure where the process vino-serv is coming from as I am unable to locate it, execute it or start it as a service.
Maybe I can bypass the UI and start it manually with the right configuration or maybe there would be a much easier way.
Not sure if changing the port to an open port (most ports are closed on the router) and setting upnp to true will solve the port forwarding problem but right now I can't even try and see if it makes any difference.
{UPDATE]
Due to ali asgher answer I would like to add that even though the default config does not allow interaction (view-only) there will be situations where the viewer needs to take control over the desktop.
[UPDATE]
I used the chrome remote desktop add on and had to install some binaries on fedora:
sudo dnf install chrome-remote-desktop.x86_64
================================================================================
Package Arch Version Repository Size
================================================================================
Installing:
chrome-remote-desktop x86_64 59.0.3071.104-1.fc25 updates 10 M
chromium-libs x86_64 59.0.3071.104-1.fc25 updates 50 M

xorg-x11-server-Xvfb x86_64 1.19.3-1.fc25 updates 860 k
Still have to test it with someone to see if the other person can control my desktop.
