This is the reason for the issue as now the Nat driver for VirtualBox is confused by the fact that the host and guest addresses are from the same subnet. Looking at your host's WiFi adapter's IP address you will find that the address assigned to it is from the 10.0.2.0/24 network range as well. In that case the guest is assigned to theĪddress 10.0.2.15, the gateway is set to 10.0.2.2 and the name server can be found at When there is only one NAT instance active. This issue is essentially due to a the allocation of the same IP addresses to both the Host WiFi adapter (by the wifi router's DHCP server) and the Guest interface (by the VirtualBox DHCP server under Nat networking).įrom the VirtualBox documentation about the integrated DHCP server Fine-tuning the VirtualBox NAT engine: In NAT mode, the guest network interface is assigned to the IPv4 range 10.0.x.0/24īy default where x corresponds to the instance of the NAT interface +2. But this didn't work either - the guest was unable to ping the router and the host got automatically assigned a different IP address after a Finder alert appeared saying that another computer on the network was already using the same IP address. Taking all those points into account and trying not to complicate things, I thought I'd start over from the beginning again and the easiest option seemingly was to set-up a bridged adaptor connection and then (in Windows XP) manually specify the same IP addresses that the host has been assigned. In the Virtualbox preferences I also tried adding a host-only network and switching on the DHCP server, but when I ping any of the IP addresses used in the default configuration I just got either a 'request timed out' or 'destination unreachable' message.Īs a last resort I tried installing the guest additions but this stopped Windows from even being able to boot so that doesn't seem to be an option either. Is Windows XP supposed to retrieve its settings from an in-built DHCP server in Virtualbox or do I need to manually specify the IP address and gateway? If so, how do I know which addresses I'm supposed to be using? I think the problem I'm having is either not knowing which settings I'm supposed to be changing or what configuration I need. My internet connection is via Airport, with the IP address of the host being 192.168.1.2 (dynamically assigned by the router) and the router 192.168.1.1. I have been trying (and failing) to set up any kind of internet connection for my Windows XP virtual machine and would appreciate some assistance.
