How to configure 2 Gateways for 1 Workstation?

Hi guys, i’m using Virtualbox. So How to run two gateways in a single working station?.

My PC → Gateway 1 → Gateway 2 → Virtual Workstation.

Is it possible to do that? If yes, can you tell me how?.

Could someone tell me exactly how to do this? What settings do I need to make? I only have access to the internet on gateway 1 which passes to my workstation, but I can’t get traffic from gateway 1 to pass to gateway 2 and then passes it to the workstation, how do I do that?

Unsupported.

Is this setting incompatible or just plain dangerous? Would it be possible or is it impossible?

Discouraged as per:

Unsupported means just only that. Unsupported. Doesn’t mean impossible.

The Tor network would likely reject the traffic. I have unintentionally used Tor over Tor outside of Whonix and it results in Nyx spitting out warnings and zero successful connections.
