Virtualbox NAT Network port forwarding refuses connection
I created a NAT Network in VirtualBox and from the Ubuntu host I am trying to SSH into the Ubuntu server VM, but I get connection refused. The Ubuntu server VM is connected to the NAT Network using port forwarding. I can connect successfully with port forwarding if I set NAT instead of NAT Network in the adapter, but for this assignment I have to use NAT Network.
Can anybody help? I have already spent many hours trying to solve this. I think the problem might be with the Ubuntu host and not with VirtualBox, but still can't figure out the solution.
Host: Ubuntu 18.04.1. LTS
VirtualBox: 5.2.18_Ubuntu r123745
Guest: ubuntu-16.04.5-server-i386

debug1: connect to address 127.0.0.1 port 1022: Connection refused

Update
- I have changed the entry port for the forwarding from 1022 to 10001, because with port 1022 forwarding wasn't working with NAT either.
- When I use port 10001 for forwarding, I can see the on the host VirtualBox is actually listening on that port:
root@giacomo-ThinkPad:~# netstat -tulpn
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 192.168.122.1:53 0.0.0.0:* LISTEN 1489/dnsmasq
Instead when using the same forwarding rules with NAT Network, VirtualBox is not listening. So it looks like the problem might be in VirtualBox?

The problem was solved by installing VirtualBox 6.0. With it everything port forwarding from localhost:10001 started working also with NAT Network.
