I gather that you want to use the fact that the resolver happens to try one address after another, in the order that they are listed in resolv.conf, as a way of giving precedence of one domain name system (the service provided over the br* interfaces) over another domain name system (the one serving the Internet and accessible by the forwarder on your machine at 127.0.1.1). That's not how DNS or the resolver were meant to be used and hence that is not implemented by the default system configuration. Given your aims, it's up to you to configure /etc/resolvconf/interface-order so that br* is listed before lo*.

When I now bring up the bridge interfaces using: sudo ifup br0 br1 Then they show up fine in "ifconfig". BUT "dns-nameservers 192.168.10.2" and "dns-nameservers 192.168.0.2" DO NOT show up in "/etc/resolv.conf" WORKAROUND: Until this has been fixed the following workaround works fine for me: sudo vi /etc/resolvconf/interface-order #Add the following entry (this entry can be put on any line BUT it has to come before the last entry "*"): ... br* ... * PS: Based on the workaround in "/etc/resolvconf/interface-order" I think the issue is in package "resolvconf" otherwise I would have reported the error against the "ifupdown scripts".
