Once when I was a contractor for a client I had my employer laptop and my customer laptop.
I did a P2V and virtualized the ThinkPad to fit in a VM on my Linux Chromebook and shrunk it all down. That and using a Google Voice number the customer never knew when I was traveling out of country
On a different situation where certain websites only visible on site I left work laptop on ethernet at office, had a Linux service running on Windows which kept a persistent SSH outbound on 443 to a Linux server at home. Then I could do a client SSH connection forwarding the ports and this access the corporate network from my tablet from anywhere.
Non-geeks don’t understand but a geek can be anywhere.
Also can bypass firewall blacklists just add a SOCKS port to your SSH client.
