When I said "real" IP Addresses, I was referring to the fact that hosts on the PRO network refer to hosts on the PSN by the IP addresses that have been assigned to these hosts, rather than referring to them by a NAT address. The "real" address may very well be a private (RFC1918) address.
In contrast, hosts on the PSN cannot directly address hosts on the PRO network -- there must be a tunnel and filter to allow hosts on the PSN to contact hosts on the PRO, just as there must be a tunnel and filter to allow hosts on the EXT to contact hosts on the PSN.
