 +====== 1:1 Network NAT ======
 +
 +With 1:1 NAT you can Map a whole network IP-range into another. This can be handy if you want to maintain a common local ip range like 192.168.1.0/​24 but also have the possibilty to connect to each IP from the outside
 +
 +{{:​configuration:​1-1nat.jpg|}}
 +
 +Common Example: A Tram installed with a lot of devices like: ticketmachines,​ videocameras or WLAN Accesspoint. The local technican wants to connect ​
 +  * to the ticketmachine via **192.168.1.13**, ​
 +  * to the videocamera via **192.168.1.14**
 +  * and the WLAN accesspoint via **192.168.1.15**. ​
 + 
 +But in the same moment you want to have a remote connection via WLAN and connect to each tram and device idividually. So would you want to have IPs like:
 +
 +  * to the ticketmachine via **10.10.123.13**,  ​
 +  * to the videocamera via **10.10.123.14**
 +  * and the WLAN accesspoint **via 10.10.123.15**. ​
 +
 +Where 123 would be your vehicle/​tram number. So each tram and device can be addressed directly.
 +
 +To avoid creating 3 or even more NAPT rules you can use the network based rules and do this with only 2 Rules. ​
 +
 +===== Basic Napt Rules =====
 +
 +  * Inbound: Map 10.10.**123**.0/​24 to 192.168.**1**.0/​24
 +  * Outbount: Map 192.168.**1**.0/​24 to 10.10.**123**.0/​24
 +
 +===== Configuration =====
 +
 +To Configure this scenario all you need are two rules
 +
 +  * Inbound NAT Rule
