Can not connect to Oracle 12c in the guest - Virtualbox 5.x - Host Mac OS Sierra 10.12.5 - Guest Windows 7 Ultimate

Description
I am using a host Mac OS X Sierra 10.12.5 and I have a guest with Windows 7 Ultimate installed and I can not connect from the host to the Oracle 12c R1 installed on the guest. I also have MySQL and DB2 installed in the guest and I can connect to both of then with no problem. Windows Firewall is off. The ping works with host pinging the guest. If I access Oracle from inside the guest it works ok also. I have already tryied to use NAT and Host-only Network adapters and none of them work. I have had this machine working since I used host Mac OS X Mountain Lion 10.8 with Vitualbox 4.3, it worked perfectly. When I updated to Mac OS X Sierra 10.12.5 I had to update the Virtualbox to 5 and than I started to have this problem that is still the same on Virtualbox 5.1.24. I have already tryied to install Windows 10 in Virtualbox 5.1.22 and had the same problem.
The error that I receive when I try to connect is: Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection.

I was expecting to listen on port 1521.
The netstat -n says:
Active Connections Proto Local Address Foreign Address State TCP 127.0.0.1:1521 127.0.0.1:49169 ESTABLISHED TCP 127.0.0.1:49169 127.0.0.1:1521 ESTABLISHED

Please, can you provide packet capture from the guest side taken while you try and fail to connect to the database from the host.
Start
tcpdump -w bug16944.pcap -U tcp port 1521
in the guest and then try to connect from the host. After connection fails, kill the tcpdump with ^C.

This is the packet capture:

I tried to connect twice.

Sorry what I mean to ask was the output of netstat -an (note the -a). It looks like your oracle instance only listens on the loopback.

No problem. This is the netstat -an:

Thanks and my apologies again. So, right, as I expected it's listening only on the loopback:
TCP 127.0.0.1:1521 0.0.0.0:0 LISTENING
so this is a problem with configuration of your Oracle instance.
You can check that your MySQL and DB2 are listening on 0.0.0.0:port (whatever their port numbers are), which is a wildcard address - so you can connect to them from outside the VM.

Thank you vushakov!!! Its is strange because it has changed when I updated...
