Network Bridge Configuration

[RedWraith]

Hi !

I am currently trying to establish a bridged network connection between my host and my guest system. I am using the following Systems:

Host:

Code: Select all

Win Vista Business x64
IP:       192.168.1.4
Subnetz:  255.255.255.0
DNS:      192.168.1.100
Gateway:  192.168.1.100

The real and the virtual Networkadapter are bridged (rightclick -> bridge)

Guest:

Code: Select all

Ubuntu 8.10
IP:       192.168.1.41
Subnetz:  255.255.255.0
DNS:      192.168.1.100
Gateway:  192.168.1.100

VirtualBox:

Code: Select all

Network connection is set to Hostinterface
and a new Hostinterface was created and bridged
with the real adapter.

The Internet and Network connections works fine for the Hostcomputer, except for the guest system, which is unreachable. Also, i can't reach any other computer from the guest system. I have tried turning the windows firewall off, but that didn't work. Does someone have a clue what i might have missed ?

I am really looking forward to hearing from you guys.

im having this exact same problem! internet worked fine when sharing was on then as soon as i bridged them i couldnt get to the internet on ubuntu

It is official, i am an idiot.

It was so simple that i didn't come up with it right away

Well, it seems the network adapter emulated by VirtualBox was somehow responsible for my problem. I used to emulate the "PCnet-FAST III (Am79C973)" Adapter. Well, i changed it to "Intel PRO/1000 MT Desktop (82540EM)" and after starting and reconfigurating the network connection everything worked right away

are you running an intel cpu?

[RedWraith]

Yeah, i have an Intel Core 2 Duo.

are you running an intel cpu?

Does that matter? The network adapter is not bound by your CPU. I have an Intel CPU on my laptop and AMD on my PC, VMs are transfered between the two and use the Intel/PRO 1000 NIC. No problems with that.
