how to proxy to containers behind nat?

ansible 1.9.4 from pip on os x.

make an lxc host with no other purpose. all the containers are behind nat, so cant directly ssh to them, but i can ssh to the physical host.

this works, ssh n.n.n.n -o “ProxyCommand ssh lxctest -W %h:%p”

and so does ssh n.n.n.n -F sshoptions, which looks like this,

`
Host *
User root
ProxyCommand ssh lxctest -W %h:%p

`

how do you get that into the inventory? i tried group_vars/containers

`

ansible_ssh_common_args was introduced for 2.0 and does not exist in 1.9.4.
