I assume you are talking about the protection to the current running "public facing" servers, hence the NAT could not provide more protection to them compares to a proper configed firewall. However, for a small business who does not have its own ASN & Provider Independent IP block(s), a NAT (NAT44 and NAT66) could provide lots of protection on IT resources when there is a need to install multiple Internet access lines for providing quickly failover (manual or automatic, doesn't matter) and/or load-sharing capability to end users. -- Michel~
