Get TCP port from add-on out to host?

Hi all. Started using HomeAssistant this weekend, loving it for now! I installed the OS image in a virtual machine on my server, and everything seems to work OK.

My question is: I also installed the Almond add-on. That addon says it runs a server on port 3000. However, if I try to access that port on the virtual machine, it does not connect. Now I can imagine this is because of a fair amount of reasons, but my prime suspect would be that Almond is running in its own little container (Docker image?) inside the Home Assistant OS, and the port is not forwarded by the main OS. Is there any way I can fix this?
