No, that unbound is in fact running locally and can be reached fine.

No and yes. It was not a matter of routing and NAT/FW/etc. It was do-tcp set to no and upstream requirig TCP to deliver an answer. Unbound then tries to do TCP even if do-tcp is set to no and that times out. So, yes it has to do with TCP, but no it is not something that happens outside of unbound as Joe suggested.
As soon as I set do-tcp to yes, everything worked fine.
