update: actually it is intel pro1000 MT network adapter

I have followed each step as in the guide and then started my VM running windowsxp. After that i intalled driver for intel pro100 MT network adapter.It then started to configure the ip but failed with limited connectivity .I then tried to configure it manually to 192.168.0.1 but still no connectivity…Please help me with this problem ASAP as i need to run some “cant do without” application in windows to connect to the internet.

Great work, many thanks, does it works with Ibex without modifications too?

This description beats all others I have found because it is so logically structured and best of it all: it works.

It made clear, that the bridge has the exact settings as the eth0 interface it bridges to and also how to configure the guest Network settings (as a normal physical machine).

My configuration: Host: Ubuntu 8.04.1, Guest: XP SP2
Host can ping guest and vice versa. Host can see shared files from guest and guest can work with samba share from host!

Thanks a lot.

Thanks so much for this guide. It was, by far, the best and most clear instructions of any that I had run across and worked perfectly on the first shot.

Oh, i solved this problem!
The solution was to set intel host interface and setup drivers :)
Thx again!

when i look at status of Network Connection – there are none of packets received and some amount of packets sent.

I have done all this staff on host Ubuntu.
My ubuntu guests work perfectly in network, so thx a lot.
But!!!
In the same time, my windows XP guests dont see anything in network except themselves((( Even internal network dont work. What should be done?

Just fyi for any others having issues with host networking. . .
I was unable to get any connectivity between the host and my windows xp guest using the default network card. Changing to one of the other virtual network cards in vbox guest settings fixed this.

Cheers

Many thanks for setting that out so clearly and concisely. By the time you’ve read through a 50-thread discussion of blind-leading-blind, with a tricky issue like this, your head is spinning. So its a great relief to get a well-defined method that just works. Well done.

I have followed the instructions. Upon restarting my network I get an error message stating the br0 bridge was not found. Any suggestions?

Thanks

Thank you. I like the way you’ve broken the instructions up into sections. It helped me more clearly see the logic of how it’s configured.

You rock for posting this. I have viewed at least twenty posts on this subject and fuxored my network settings at least four times — yours is the first solution that worked. Kudos, sir!

Hi,

Worked first time even though I am using the AMD64 bit version. Great stuff.

Thanks for posting it.

Good day,
I would like to provide a detailed post of settings on my machine and would appreciate it if anybody can give me some insight into why my tap0 interface isn’t transmitting any data.
I’ve managed to get NAT networking going and my Guest OS is happily communicating. The trouble seems to be with the ‘Host networking’ setup.

VirtualBox configuration (1.5.6-28241_Ubuntu_gutsy) on Kubuntu (ubuntu 7.10)

Guest OS
Windows XP, sp2
Network settings: Set to DHCP, firewalled
(NAT from guest to host works fine)

The tap0 interface itself at the moment can’t see the rest of my local LAN – I guess getting this to work will solve a lot of the problems already.

Note: I’ve also tested the tap0 interface with
/proc/sys/net/ipv4/ip_forward == 1 and …==0,
making no difference to the connectivity.

Any help would be appreciated.

Aaack! Should have check guest firewall before post #28.

I _could_ connect by IP w/rdesktop from the host and network to the guest. But I could not ping.

After I turned off the firewall on the WinXP guest, I could ping and rdp by WINS name.

If reconfigured the firewall on guest to allow all ICMP traffic and allowed Exceptions for “File and Print Sharing” and “UPnP Framework”.

Now with firewall up, have full access to guest by WINS name.

I’ve tried the VBox user manual and several different methods for HIF I’ve found online (including yours) and I still get the same effect as NAT. I cannot connect or ping from network to guest.

VBox: PUEL 1.5.6 w/ guest additions
Host: ubuntu 7.10 gutsy
Guest: WinXP Pro SP2

Could this be a firewall issue?

JeSTeR: Yes, that’s one way of saying it. With host networking the guest is a regular member of the same ethernetwork that the host is.
