I am asking because I am not sure how those public/bridged etc. networking 
between host/guest works. Sometime I cannot see the port on the host. Maybe 
it is because the app in the VM is restricted to accept localhost 
connection only, but I always strugling to find the exact place of the 
error.

Are those option equal ?
call 192.168.10.101:80 on host machine
make port-forward 80:80 and call localhost:80 on host machine

Is the first option using NAT while the second is not?
