Best way to tunnel home from my job site network

Hey friends,
whats the best way to tunnel home to my proxmox to use a linux wm for surfing on reddit at work?
I can use tailscale via browser, which works, but i think my IT can detect this tunnel and stresses me. im working at a big company. >10.000 worker there.
I rented a external server to bond my dsl and 5g, maybe i can use this?
I have no homeoffice atm so please help a mate.
