I've installed Ubuntu (both desktop and server, newest releases) on VirtualBox virtual machines.
They are working, all services is running (apache2, mysql, php, xrdp, ssh...), i can even open apache2 default page in feuerfox on desktop system's localhost.
But then i trying to access it via lan between VM and host-machine.
And apache2 page doesn't opening, mysql and rpd clients can't connect and even ssh connection "refused".
When installing, ethernet interface is automatically configured for DHCP (as i use VirtualBox's NAT to access internet for installing optional packages), but then i changing configuration to static LAN IP's so VM and host can ping each other.
Firewall deactivated, but it doesn't help.
UPDATE [ROARING INCREDIBLY LOUD]
Found it by myself.
Problem was just that i used static network 192.168.1.0 on interface to VM, when the same network was assigned to other interface to DSL modem by it's DHCP. So VM/HOST was 192.168.1.2/192.168.1.1 and host/DSL was the same 192.168.1.2/192.168.1.1.
