Configuration of Windows XP for port forwarding
The settings of the port forwarding can be done in the Windows Firewall. Go to the “Advanced” tab and select the LAN connection which connects the host and the target. Click on “Settings”.

For TFTP this is the following data:
- Service description: Trivial File Transfer Protocol (TFTP)

Copying of virtual machines
When copying virtual machines, it may be that a new Ethernet device with a new MAC address is created. If the Ethernet device gets a new name (eth2 …), you have to add auto to the name of the interface in the file etc/network/interfaces (e.g., auto eth2). Then the service networking must be restarted (sudo service networking restart).
Alternatively, you can edit the file /etc/udev/rules.d/70-persistent-net.rules and assign the MAC to the eth0 device.
