Visit node-red dashboard outside of local network

I am trying to view my node-red dashboard outside of the local network. This is coming from my Raspberry Pi 3. Would this be possible through a website like dataplicity? If so I am unsure on how to get node-red to serve the dashboard on port 80, as that is the location of the wormhole. Thank you.

Unfortunately the IT department has this site blocked due to content filtering. Will not be able to use this.

I assumed you were on a private connection, surely your IT department can provide a VPN connection from outside?

Yes, I will have to mention this to them.
