Can't access guest OS from outside

[eagle007]

I've bought a Dedicated Server. Here is the details:

Main IP: 173.208.244.aaa
Subnet Mask 255.255.255.248
Gateway 173.208.244.xxx
Usable IP: 173.208.244.aaa - 173.208.244.eee

I've installed Debian 8 on this Dedicated Server then installed VirtualBox.

I need to create 4 VPS in this VirtualBox. It would be Ubuntu 16.04, Windows Server 2008, CentOS 7, etc...

I then installed Ubuntu 16.04 as guest and assign IP 173.208.244.bbb . But I still cannot access this guest web server or access SSH into Guest from my laptop.

As I stated above, I will assign this IP 173.208.244.bbb to my Ubuntu guest. This is my is my Network Interface of Guest OS (Ubuntu 16.04)

This is my Debian 8 (host) network interface

Code: Select all

auto eth1
allow-hotplug eth1
iface eth1 inet static
	address 173.208.244.aaa
	netmask 255.255.255.248
	network 173.208.244.yyy
	broadcast 173.208.244.zzz
	gateway 173.208.244.zzz
	# dns-* options are implemented by the resolvconf package, if installed
	dns-nameservers 127.0.0.1
	dns-search <host_of_my_provider>

auto vmbr0
iface vmbr0 inet static
	address 173.208.244.aaa
	netmask 255.255.255.248
	bridge_ports none
	bridge_stp off
	bridge_fd 0
	up route add -host 173.208.244.bbb dev vmbr0
	up route add -host 173.208.244.ccc dev vmbr0
	up route add -host 173.208.244.ddd dev vmbr0
	up route add -host 173.208.244.eee dev vmbr0

And these are my VirtualBox Settings

I also installed Nginx in it. I use this command on Guest

Code: Select all

curl localhost

The Guest can open the default Nginx webpage easily.

But when I access from Host or from my home computer, It says:

Code: Select all

curl: (7) Failed to connect to 173.208.244.bbb port 80: No route to host

What is the correct configuration of network interface, port forwarding, bridge settings, etc...?
