Hello.
How can I SSH to VM that it's network configuration in NAT? My host is "Debian 8.6 x86_64" and VM is "CentOS 7.6 x86_64". The VM IP address is "10.0.2.15" and I set a secondary IP address to my NIC as below:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
auto eth1:0
iface eth1:0 inet static
address 10.0.2.14
netmask 255.255.255.0
broadcast 10.0.2.255

eth1:0 Link encap:Ethernet HWaddr 00:11:3b:15:4a:32
inet addr:10.0.2.14 Bcast:10.0.2.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
But I can't ping "10.0.2.15". What is my problem?
Thank you.
If you're using NAT then you need to configure port forwarding on Virtualbox, i.e. that a given address/port combination at your host should map to address/port combination within VM. This is not a debian problem but a Virtualbox issue.

Well, how can we answer that?
In your first post you say you've configured eth1:0 with an IP address. You didn't ask why you did it and we can't possibly know that.
Maybe you one (or a few) steps back and tell us what you're try to achieve?
Otherwise we may end up solving a problem that is only there because you think you need a specific solution to another problem...
(In general, if you need a secondary IP address * for a VM guest * it wouldn't cost you anything to tell VirtualBox that you want TWO ethernet interfaces -- they are virtual and don't cost anything! :) -- instead of assigning multiple addresses to an interface.. but again, first tell us what you want to do and why you (think you) need two IP addresses..)

My problem Solved. I thought that I should set another IP address to my NIC in VirtualBox VM range.
