Is it a problem if they have one ? If it is possible, you can route via this private address on your FreeBSD installation to the new one and assign a public/32 to the last. Alternatively to doing routing like above, if you have a firewall enabled on the first machine, you can do address forwarding between the first and the new one. And last, maybe with something like -iface from "route" you can achieve what you want. K.
