after installing ubuntu in virtualbox using NAT the guest system has the IP 10.0.2.15. its possible browse and to ping the host
in the global settings i found a virtual host-only interface with an IP 169.254.203.239. this seems to be the IP of the virtualbox "router" - ping is possible what i know what works is using an forwarding to some ports get access to the guest system.
but - as i remember of vmware - i want to have access to the guest, as its like a physical one. so i tried to give the guest (ubuntu) an ip from my host net (192.168.178.x)
as a result a can no more browse and no ping is possible
i only added:
auto eth0 iface eth0 inet static address 192.168.178.155 netmask 255.255.255.0 gateway 192.168.178.1
to etc/network/interfaces - nameserver is in etc/resolv.conf
