Simple script to automatically set up port forwarding for LXC containers
Copy lxc-portforward, lxc-portforward.conf, and lxc-portforward-helper to /etc/lxc.
In your container config set:
lxc.network.script.up = /etc/lxc/lxc-portforward
lxc.network.script.down = /etc/lxc/lxc-portforward
Edit lxc-portforward.conf to forward the ports you want forwarded
Port forwarding information is stored in /etc/lxc/lxc-portforward.conf. Format is:
container_name:local_port:remote_port
IP addresses are stored in /var/run/lxc-portforward/ so when the container is stopped the proper iptables rules can be removed.
