When you use “lxc-destroy” to get rid of a container, it doesn’t clean-up the DHCP lease from DNSMASQ.  To do that you need to remove the reservation from the cache which is in /var/lib/misc/dnsmasq.lxcbr0.leases – once you do that, you need to bounce the DNSMASQ service with ” /etc/init.d/dnsmasq restart ”

to change container start parameters, edit the file /var/lib/lxc/container_name/config

lxc.start.auto = 1 (to auto-start)

lxc.start.delay = 0 (in seconds)

lxc.start.order = 0 (higher means earlier)

Example of port forwarding into a container (You don’t want to do this on port 80 if your using reverse proxy.  Host can already pass traffic to lxc containers)

iptables -t nat -A PREROUTING -i eth0 -p tcp –dport 80 -j DNAT –to 10.0.3.143:80
