(Get the code!)
Note I tested this on vivid with a /downitpables script containing:
#!/bin/sh
LXC_BRIDGE=lxcbr0
LXC_NETWORK=
use_iptables_
iptables -w -L -n > /dev/null 2>&1 || use_iptables_
iptables $use_iptables_lock -D INPUT -i ${LXC_BRIDGE} -p udp --dport 67 -j ACCEPT
iptables $use_iptables_lock -D INPUT -i ${LXC_BRIDGE} -p tcp --dport 67 -j ACCEPT
iptables $use_iptables_lock -D INPUT -i ${LXC_BRIDGE} -p udp --dport 53 -j ACCEPT
iptables $use_iptables_lock -D INPUT -i ${LXC_BRIDGE} -p tcp --dport 53 -j ACCEPT
iptables $use_iptables_lock -D FORWARD -i ${LXC_BRIDGE} -j ACCEPT
iptables $use_iptables_lock -D FORWARD -o ${LXC_BRIDGE} -j ACCEPT
iptables $use_iptables_lock -t nat -D POSTROUTING -s ${LXC_NETWORK} ! -d ${LXC_NETWORK} -j MASQUERADE || true
iptables $use_iptables_lock -t mangle -D POSTROUTING -o ${LXC_BRIDGE} -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill
I raun /downitpables, then did 'sudo stop lxc-net', which succeeded. Then did 'sudo start lxc-net', which succeeded.
