Prestige 324 Intelligent Broadband Sha ring Gateway NAT 11-1 Chapter 11 Network Address Translation (NAT) This chapter discusses ho w to configure NAT on the Prestige. 11.1 Introduction NAT (Network Address Tran slation - NAT, RFC 1631) is the translation of the IP addr ess of a host in a packet, e.
11-2 NAT NA T never changes the IP address (e ither local or global) of an outsi de host. 11.1.2 What NA T Does In the simplest form, NAT changes the source IP address in a packet recei ved from a subscriber (t he inside local address) t o another (t he inside global ad dress) befo re forwardin g the packet t o the WAN si de.
Prestige 324 Intelligent Broadband Sha ring Gateway NAT 11-3 Figure 11-1 How NAT Works 11.1.4 NA T Application The following figure illu strates a possible NAT applica tion, where three inside LANs (logical LANs using IP Alias) behind the Prestige can communicate with three distinct WAN net works.
11-4 NAT Figure 11-2 NAT Application With IP Alias 11.1.5 NA T Mapping T ypes NAT supports five types o f IP/port m apping. They are: 1. One to One : In One -to-One m ode, the Prest ige maps one local IP address to one gl obal IP add ress. 2. Many to One : In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP address.
Prestige 324 Intelligent Broadband Sha ring Gateway NAT 11-5 3. Many to Many Overload : In Many-to-Many Overload mode, the Prestige maps the multip le local IP addresses to shared global IP addresses. 4. Many One-to-One : In Many One-to-One mode, the Prestige maps the each local IP addresses to unique gl obal IP add resses.
