Create a HTTPS Tunnel to avoid network hard limitations

Here is my problem : At work, if I don't want to use my phone for everything I use the provided connection to the internet, that goes through a network that has strict restrictions : basically all protocols besides HTTPS are blocked. It's been a hassle and has prevented me to work efficiently several times, but despite my complaints to the administration the rules are nowhere near changing. So what I am thinking I could do : Create a HTTPS Tunnel to a personal computer at my place (Raspberry pi I just acquired) to be able to do anything I can do from my place. I am posting the question here because the computer I use between my work and my home runs on macOS. 1. Are there people here that would know if channeling all my connections through such a tunnel could be done (like using a proxy) ? 2. Do you have a better idea ? (Yes I thought about using a VPN, but that protocol is blocked too) 1.st Challenge : I don't know thing one about Tunnels 2.nd Challenge : Connecting the Raspberry Pi at my place to be securely accessible from outside my home network. Thank you already for enlightening me.
