How to set up Ubuntu server on Virtual Box?

Question

virtual box

Hello.
The situation is like this, I have ubuntu 14.04, it has a virtual box, Ubuntu Server is installed in VB, openssh-server is installed on it, the network is configured as follows:


ifconfig output:

I have Internet from a mobile modem.
Problem - the server does not ping. Outside, i.e. with Ubuntu 14.04 I can’t reach the server via ssh, I enter ssh [email protected]and nothing happens.
How to solve this problem?
upd:

Answer 1

For NAT connection: Advanced (Advanced) -> Port Forwarding -> forward port 22 (well, or the one on which sshd is configured in ubuntu server) to one of the free host machines
After that, you can connect to Ubuntu server like this
ssh [email protected] -p 25000
