I had this all figured out, and now it won't work again, so I'm here to ask for advice. I recently had to reinstall my OS (openSuSE 10.3) and ended up reinstalling VirtualBox as well. I'm now attempting to restore my bridge to where it was before I had to reinstall. I've done the following so far as the steps relate to the User Guide:

1. Ensure that my user has access to /dev/net/tun. My user is a member of the vboxusers group.

Code: Select all

linux-m7ac:~ # ls -l /dev/net/tun
crwxrwx--- 1 root vboxusers 10, 200 Sep 21  2007 /dev/net/tun

2. Create an bridge interface, modify the bridge to include my eth0 interface, and bring up the bridge.

Code: Select all

linux-m7ac:~ # tail -n 20 /etc/sysconfig/network/ifcfg-eth0
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IFPLUGD_PRIORITY='20'
IPADDR='0.0.0.0/32'
MTU=''
NAME='Dell BCM4401-B0 100Base-TX'
NETMASK=''
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='manual'
USERCONTROL='no'
PREFIXLEN=''
linux-m7ac:~ # tail -n 20 /etc/sysconfig/network/ifcfg-br0
BOOTPROTO='dhcp'
NETMASK='255.255.255.0'
STARTMODE='manual'
USERCONTROL='no'
DHCLIENT_TIMEOUT=30
BRIDGE='yes'
BRIDGE_PORTS='eth0'

3. Create the virtual interface vbox0 via VBoxAddIF and make sure it is included in the bridge.

Code: Select all

linux-m7ac:~ # brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.00188bbd2320       no              eth0
                                                        vbox0

4. Add my ethernet bridge to the necessary location on the firewall to forward ports.

Code: Select all

linux-m7ac:~ # tail /etc/sysconfig/SuSEfirewall2
# order to install special permitting rules for them.
#
# Format: list of interface names separated by space
#
# Example:
#   FW_FORWARD_ALWAYS_INOUT_DEV="xenbr0"
#
FW_FORWARD_ALWAYS_INOUT_DEV="br0"
FW_SERVICES_ACCEPT_INT=""
FW_SERVICES_ACCEPT_DMZ=""

I'm currently able to enable my bridge and I receive an IP address on my host machine. I do not receive an IP address on my guest machine (XP Pro). It seems like I followed all the same steps I did last time, but for some reason I'm missing something. I'm open to suggestions. Thanks in advance,

---EDIT---

I was able to get this working by reading a couple of the other posts and incorporating some of their suggestions. Everything actually started working after I changed the line in my bridge setup from BRIDGE_PORTS='eth0' to BRIDGE_PORTS='eth0 vbox0'. I also changed to the Intel virtual nic driver, but that didn't seem to have any impact by itself. Amazing what you can accomplish when you read, eh?

Did you make it auto set the bridge on bootup or do you have to type this out everytime you boot?
