nginx git configuration

Hi to all,

I tryed to configure nginx to forward request auth to my git repository , that i ve setup with ssh key authentication.
I ve try this solution but that not works fine for me .

My nginx server has a public ip and i have to set proxypass auth to my git repo that reside in other location that is reacheble with private address. i need that that the public url with /location, forward the authetication with ssh key at port 22
the proxypass auth must works with gitbush or throw git bush .
how i can do that ?

anyone have do that configuration in our environment ?
