* Need ssh client to request a secure connection and a running ssh server to process the secure connection. The key for me was to realize that ALL connections was PASSING-THROUGH intermediary devices to get from my remote PC to my guest virtual-machine at home -Hence port forwarding! Remote device (leave ssh port 3022) -> INTERNET -> MODEM -> ROUTER (FWD frm:p3022 to:p3022)-> HOST MACHINE (FWD frm:p3022 to:p22) -> GUEST VM (arrive ssh port 22) Remote device (ssh client) -> PASS THRU DEVICES -> GUEST VM (ssh server) Remote device -> INTERNET -> MODEM -> ROUTER -> HOST MACHINE -> GUEST VM I add a few more step in case it might be helpful to someone else: You should be able to connect using computers, tablets, and smart phones (android, IPhone,etc). helped me to accomplish the task of connecting from out on the internet to my home computer's guest machine.

If not, you may run sudo ifdown enp0s8 & sudo ifup enp0s8

You should see your ip: $ ip addr show enp0s8 You should see three interfaces like lo, enp0s3, enp0s8. Modify /etc/ssh/sshd_config so there is PermitRootLogin yes Preserve those settings upon reboot # vi /etc/hostname.e1000g1Ĭonfigure ssh service ( administering) to login as root (not adviced)Ĭheck if ssh is enabled # svcs -a | grep ssh

Check from host if this interface is reachable: ping 192.168.56.10.Second adapter in guest should also be in 192.168.59.*. You should see lines: Ethernet adapter VirtualBox Host-Only Network: First adapter should be Nat, second Host-only.
