My intention is allow my ethernet interface to be allocated as many IPs on my local network as necessary to service the virtual machines I'm running. The "bridge", in this case, is a virtual-to-physical one. >> This is my current /etc/network/interfaces: >> >> # The loopback network interface >> auto lo br0 >> iface lo inet loopback >> >> # bridging iface br0 >> inet dhcp >> bridge_ports eth0 >> bridge_stp off >> bridge_maxwait 0 >> bridge_fd 0 >> >> >> I must be missing something simple here.

I did look at those. And by following that configuration: # Set up interfaces manually, avoiding conflicts with, e.g., network manager iface eth0 inet manual iface eth1 inet manual # Bridge setup iface br0 inet dhcp bridge_ports eth0 ... Network Manager cannot control eth0. Under "Wired Networks" it reports "Device not managed". Besides, the comment in that configuration is "# Set up interfaces manually, avoiding conflicts with, e.g., network manager" - so it's clearly acknowledge here that bridging does indeed conflict with network manager, and I shouldn't expect it to work using that example. > But shouldn't be better to use the same networking method (ifup or > N-M but not a mix of them) to configure the interfaces (eth0 and > br0)? :-? Ok, so I'm getting used to the Debian way of doing things, having come from another distro. I assumed I /was/ using the N-M way of doing things, editing a N-M config file. But, I glean from your comment that there is overlap here. When I keep the above settings in /etc/network/interfaces and change /etc/NetworkManager/NetworkManager.conf, from [ifupdown] managed=false to [ifupdown] managed=true then I can control eth0 through Network Manager, and I'm back at square one - both eth0 and br0 get the same IP address, and routing breaks. I believe harmony is possible between NM and br0 - I'm just unsure of the approach in Debian. -- Steve Dowe Warp Universal Limited http://warp2.me/sd -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
