Howto: Configure Port Forwarding with NAT on VirtualBox!!

If you want to configure your sshd, follow the steps bellow:

1. First stop the guest OS

2. On CLI: type the three instructions

# VBoxManage setextradata "Linux Guest" "VBoxInternal/Devices/e1000/0/LUN#0/Config/guestssh/Protocol" TCP
e.g. ssh goes via TCP

# VBoxManage setextradata "Linux Guest" "VBoxInternal/Devices/e1000/0/LUN#0/Config/guestssh/GuestPort" 22
p.s. 22 is sshd port default value

# VBoxManage setextradata "Linux Guest" "VBoxInternal/Devices/e1000/0/LUN#0/Config/guestssh/HostPort" 2222
p.s. I'd like to apply 2222 on host OS to forward the service for me

3. Then the service is forwarded!!

P.S. e1000 is my adapter Intel PRO 1000; can be replaced according to your own settings.
