The connector with the yellow label looks like your VM connection, the other two look like satellite.
Your outside box looks like one for a fibre connection to the property (not one I am familiar with) rather than coax.
What items have VM supplied you with to make the connections?
As I understand it, the fibre converter in the box outside needs to be powered from inside by a small power supply and fed into the coax by a power injector.
This link shows an example setup that someone posted online (example only, your particular setup may differ)

Power injector is top right and power supply is the small white unit plugged into the power strip in the bottom RHS picture. Have you got those bits to hand?
Others will know more about this setup and will be able to comment further.
