[xubuntu] Access VirtualBox guest from firefox host

Hi,

I have an Ubuntu 12.04 server machine on Virtualbox , hosted on Xubuntu 12.04 .

I'm trying to access Apache from Firefox. I tried following:

On host:
>ifconfig

On Virtualbox:
file > preferences > network > new host-only network
ipv4adress is: 192.168.56.1
on the machine, settings > network > adapter 2 > "Host-only adapter"

On Xubuntu host:
>sudo nano /etc/hosts
10.0.2.15 example.local

In Firefox, I try to go to "10.0.2.15", and after some time, I get a "Server not found". I tried also "http://192.168.56.1" and "example.local"

I tried also:
on the machine, settings > network > adapter 2 > "Bridged adapter" (eth0).

I disabled firewall on both host and guest using:

$ sudo iptables -X
$ sudo iptables -t nat -F
$ sudo iptables -t nat -X
$ sudo iptables -t mangle -F
$ sudo iptables -t mangle -X
$ sudo iptables -P INPUT ACCEPT
$ sudo iptables -P FORWARD ACCEPT
$ sudo iptables -P OUTPUT ACCEPT

and

$ sudo ufw disable

I can access Internet from host and guest.

Thanks for your help!
