Ok.. after spending numerous hours searching... It appears this is the problem... https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1254338 SOLTUON Run this on the HOST sudo iptables -t mangle -A POSTROUTING -o lxcbr0 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill Rebooted one of the containers.. WORKS! Crisis over.. data reachable.... back to work.. BUT.. long term... Is this related to some isc-dhcp change? And the containers need a sudo apt- get update/upgrade to fix and thus the above won't be needed? Or for this box I need to put this into /etc/init/lxc-net.conf If so where? Is the iptables line the ONLY solution on 12.04 and 12.04 containers???? Comments???
