After cloning my CentOS VM in Virtualbox (I used the Reinitialize the MAC address of all network cards option), the original and the clone VM both now has 127.0.0.1 as their IP. Anyone knows how t. The snag occurs on the cloned VM's that are deployed from the template VM because the MAC address assigned to the eth0 interface in the udev network configuration files of these clones ends up conflicting with the MAC address assigned to the.vmx configuration files that are auto-generated by ESX server for each VM at the time of cloning. I'm currently pulling my hair out trying to setup a Layer 2 bridge between a USB wifi dongle (wlan0) and an ethernet port (eth0). The system is on a Cubieboard - it's an ARM board with embedded linux - it has an ethernet port plus two USB 2.0 ports.

I am attempting to set up my Raspberry Pi as a bridge, using Debian wheezy. I have a
hostapd.conf : (some details changed for security, and yes, I know WEP is no good)..
And this in
/etc/network/interfaces :
Everything seems to come up ok, but I cannot associate with the bridged wireless connection - even though the flashing lights on the USB stick suggest packets are being exchanged.
I have read somewhere that not all cards/devices will run in hostap mode - they won't pass packets in one direction: is that right? (The info was a bit old)- this my card:
So, what have I got wrong here?
Update: So I have done further investigations and can get the bridge up, but seemingly that destroys the (wired) ethernet connection, which is odd. E.g., on the RPi:
Boot the system..
(router) - this works
Attempt to associate with wireless LAN .. fails (or rather 'with limited connectivity' on Android phone - no good)
This just shows mac of wlan0 and mac of phone at this point
At this point I can now associate the phone with the wireless network, but..

And similarly I can no longer ping the RasPi from any other machine on the network

Suggests the bridge is dropping packets..
Any ideas?
Further update: The
/etc/network/interfaces file now (and for the above sequence) reads:

Bridges made easy:
There is a project on sourceforge made just for your situation. http://sourceforge.net/projects/bridger/ It even comes as a deb package.
With regard to 'dropping' packets:
Pure Bridge vs. Shared Bridge:
Restart the network:
sudo /etc/init.d/networking restart After making complex network configuration changes its easier to just reboot rather than make sure everything restarted properly in the reboot.
You think you have routing issues:
If NONE of this works, try that debian bridging app, and if that doesn't work then your wireless dongle doesn't support promiscuous mode. (see above)
If it works at any time here, reboot and make sure it still works.

I have some wireless bridges working on Debian Linux and Openwrt, so I am very familiar with this issue.
You missed one important command: You forgot to tell your wireless driver to transmit 4-address frames (sometimes improperly/historically called WDS), which is required for 802.11/wireless bridging. Do this with the command 'iw dev wlan0 set 4addr on'. Use a 'pre-up' statement in your Debian interfaces file on the bridge to apply it before bringing up the bridge. Note that 4-address frame mode requires driver support and some old crappy 802.11 drivers or hardware may not support it.
I also strongly suspect your problems may have been complicated by a bug in the Linux kernel which specifically affects bridged interfaces. I ran into this bug myself and had to compile my own wpa_supplicant from sources because the version in Debian is old and affected. wpa_supplicant and hostapd share a common code base, but I'm not completely sure that this affected hostapd as well as wpa_supplicant.
There is a work-around commit to the issue here:
I am under the impression this is in the 2.5 release, and I know it's in the current 2.6 source. The current Debian version is 2.4, which is broken. Please pester the Debian project to update their wpasupplicant and hostapd packages.
Here is a sample config for a wireless bridge client using WPA/WPA2 with a wireless bridge between interfaces wlan0 and eth0, with the host getting a DHCP address on the br0 interface (replace 'dhcp' with 'manual' for no IP address). For a situation where you want to be the AP, include the interface= and bridge= commands in hostapd.conf and omit the wpa-* commands below.
![]()
In your /etc/network/interfaces file:
And make sure your wpa_supplicant is version 2.5 or later. It won't work with wpa_supplicant 2.4 and current kernel versions.
I should also note that there is currently a race bug in ifup where bridge interfaces may fail to come up at boot time, but that's a whole other issue.

You seem to need ip forwarding.
try
cat /proc/sys/net/ipv4/ip_forward
If it's
0 issue: echo 1 > /proc/sys/net/ipv4/ip_forward

Bridging can only work when an interface receives all packets otherwise they will get see packets addressed only to them. Your current setup might describe a configuration for a router though but not for a bridge.
eth0 and wlan0 should have no ip addresses (meaning 0.0.0.0) and if desired, you could always use an IP address for br0 though.
Here's some official documentation also: http://wiki.debian.org/BridgeNetworkConnections
