This issue also affects the "debian" LXC template in Ubuntu (lxc 1.0.0~alpha1-0ubuntu11). If I create a Debian jessie container on Ubuntu Saucy, then the container cannot DHCP.

Workaround: sudo iptables -t mangle -A POSTROUTING -o lxcbr0 -p udp --dport bootpc -j CHECKSUM --checksum-fill

It looks like the Debian bug is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717217

Is there any way a workaround could be applied to lxc in Ubuntu - perhaps something specific to the Debian template? I wonder if the template could arrange for an iptables inside the container to mangle the incoming DHCP packet or something.
