I'm not sure whether the question's title describes what I'm trying to achieve...

Anyway, it is coronavirus outbreak, and I'm grounded at home. My employer has very strict security/hardware polices that allow only company-approved laptops (MacBooks) to connect to the most of company resources. On top of that we can connect only through VPN. At home I have pretty powerful linux machine that is collecting dust, while it can save hours of compile time/time to spin up docker containers, etc...

I have full admin access both to my Mac, Linux machine and home router, so I got the idea that I can use Mac as VPN or proxy server to connect to corporate network from my Linux machine:

Linux workstation ---- (VPN or Proxy config + some router network magic) ---> MacBook --- VPN ----> Corporate Network

Does it sound like a feasible solution?

Bonus question:

I do lots work through terminal, so it'd be nice if this setup will make it work seamless as well (i.e. can I just copy my SSH private/public keys from Mac to Linux machine or proxy SSH/CMD things as well)?

In case it matters for answer: Router: Netgear c3700 Mac OS version: Catalina 10.15.4 Linux machine OS: Ubuntu 20.04

It seems that "borrowing" mac address from the work laptop will be the easiest solution.

To lookup mac address on MacBook the following command can be used:

$ ifconfig
...
en0: flags=...
        ...
        ether xx:xx:xx:xx:xx:xx

Or via GUI: System Preferences -> Network -> WiFi -> Advanced (button) -> Hardware (tab) -> Mac Address

To set the address on the Linux machine the following command should make the trick:

macchanger -m xx:xx:xx:xx:xx:xx eth0

Installation instructions, just in case you don't have macchanger installed:

sudo apt-get update -y
sudo apt-get install -y macchanger

There are probably some ethical concerns with workarounding rules set by company's security team... I feel like asking them to allow-list your workstation would be a better solution ¯\_(ツ)_/¯.
