You need NAT whenever you can't change your peers' routing table, for whatever reason. It's used extensively in IPv4 world for LAN=>WAN connectivity because your only peer (your ISP) won't agree to send all traffic for 192.168.0.0/24 to your home. Its most popular use case disappearing doesn't make it any less useful for the narrow set of circumstances when it's basically your only option. |
