Yes, sorry I have badly explained so jail_name="thename", thename is guantanamo. My host is behind a router that provide me an internet access yes and yes 192.168.0.12 is my host ip so yes my jail share the host address. jls command show me this address but ifconfig command (in my jail) show me no address... I've read that in my case I've just need of jail_enable="YES" in my rc.conf... I will add with most of jail_guantanamo* variable and test...
