Routing Hosts Port to Whonix Workstation

Hello,

Lets say i have some service running on some port on my host. How could i route it to whonix workstation securely with KVM? I read a bit of DOCS, but i only found some information for Virtual box. Are there any risks?

Same dream here.

I followed 2 articles:

With SOCAT I can communicate between Gateway and Workstation like in the second article, but I cannot reach the Gateway from the host, I think the problem is the port forwarding.
With VirtualBox it was easy, with KVM I tried many things, but not working…
