VBoxManage natnetwork modify --netname nextcloudnet --port-forward-4 "ssh1:tcp:[]:30022:[10.19.100.4]:22"
VBoxManage natnetwork modify --netname nextcloudnet --port-forward-4 "ssh2:tcp:[]:31022:[10.19.100.5]:22"
VBoxManage natnetwork modify --netname nextcloudnet --port-forward-4 "http:tcp:[]:30080:[10.19.100.4]:80"
