-**Abstract**: Here we assume we have two FreeBSD hosts, A using public IP 1.1.1.1 and internal virtual net 192.168.3.0 for jails, and B using public IP 2.2.2.2 and internal net 192.168.6.0 for jails. We need hosts and jails to communicate together, preferably in a encrypted way.+**Abstract**: Here we assume we have two FreeBSD hosts, **A** using public IP 1.1.1.1 and internal virtual net 192.168.3.0 for jails, and **B** using public IP 2.2.2.2 and internal net 192.168.6.0 for jails.
