Another update. (This is running on Karmic beta, with dnsmasq-base 2.50-1.)
Hopefully this diagram will make sense. Client (10.42.43.11) <---> (10.42.43.1) [eth1] Ubuntu [eth0] (192.168.1.144) <---> (192.168.1.1) router <---> Internet When I boot my Ubuntu machine with both interfaces active and the network sharing turned on, then I have the problem with the DNS failures. However, if I then disable eth1 and re-enable it, then everything works. -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
