--> A Secure Network Address Translation (SNAT) is a method that changes the source client IP address in a request to a translation address defined on the LTM.
--> Secure NAT changes only source IP address it does not change the source port number.
--> Secure NAT is basically used in one arm deployment method to prevent asymmetric routing.
--> By default, the LTM attempts to store the source port, but if the port is already in use on the selected translation address, the LTM also translates the source
port.
--> Each SNAT address, like an IP address has only 65535 ports available.
--> If you require more than 65535 connections may require translation for one particular virtual server, you should configure more than one SNAT addresses (SNAT pool).
--> A SNAT pool is a group of translation addresses for a particular virtual server.
--> SNAT auto map automatically uses the egress interface IP address ( floating IP address ) for the translation.
