You shouldn't need to mess with epair for most jails.  Just specify the 
jails' addresses (ip4.addr=x.x.x.x) in your jail.conf, and be sure to 
have an "interface=foo0" global line.  The simplest jail setup is one 
using publicly available addresses on a single interface, which sounds 
like what you have.
