Machine 62... : Ubuntu 16.04, has access to internet, can be accessed via the internet. On the 62... machine, there is VirtualBox with a VM (also Ubuntu).
I'd like the VM to behave like a 'normal' machine (ip-requests). I reserved a static ipIP for it, but now I'm not sure how to configure the interfaces of the host and the guest in a way I can ping the guest-machine like I would usually ping the host machine (via the reserved ipIP instead of 62...).
ReverseProxy worked for a while, but then I needed websockets over ports I dontdon't know in advance. So now my next guess is NAT? ipforwarding? Bridged networks? Masquerading?
