nginx on host + nginx in jail - how to setup two servers?

[dong]

How to set proxy_pass? When I set NAT in pf.conf then sites from nginx
on my host dont working, but sites from jail is working :)

Its my pf.conf now:
rdr pass on em0 proto tcp from any to em0 port 80 -> 192.168.1.3 port
80
nat on em0 from 192.168.1.0/24 to any -> 188.x.x.x

192.168.1.3 - its my jail
188.x.x.x its my host
