Information About Static NAT with Port Address Translation
When you specify the port with static NAT, you can choose to map the port to the same value or to a
different value. Using the same value lets you translate ipA/port1 to ipX/port1 while translating
ipA/port2 to ipY/port2.
Figure 26-2 shows a typical static NAT with port translation scenario showing both a port that is mapped
to itself and a port that is mapped to a different value. The translation is always active so both translated
and remote hosts can initiate connections.

Note For applications that require application inspection for secondary channels (for example, FTP and VoIP),
the adaptive security appliance automatically translates the secondary ports.
