VirtualBox Networking – How to Reach a Guest from Host Using NAT

networkingvirtualbox

Using Fedora or Ubuntu for the host with firewalls turned off on each side (vbox guest&host), what do I have to do to reach the guest machine using a NAT interface just like it would be with a bridged interface? (Only from the vbox host!)

Update: ifconfig on the host machine:

# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:41:56:6B:78:4E  
      inet addr:192.168.1.2  Bcast:.192.168.1.255  Mask:255.255.255.0

Best Answer

According to this documentation, current versions of VirtualBox do not expose the internal NAT interfaces to the host machine. You may configure special port forwarding rules to reach the boxes, but even the host is not able to reach the whole interface. You should used bridged networking for that.
