Differences bw SNAT and Auto map

 Differences bw SNAT and Auto map :-

SNAT= Secure NAT.
Secure nat will use for symmetric routing.
Ex.
Path A Path B
Client----> F5---> Server<--Internet--Client.

Server to client reply will not go through the Path B.

For that on the F5 u need to enable "auto-map"

While client request will coming from F5, it will get NAT with local interface. Because of NAT server will think this is my local network let me give reply. Once reply given by server It will check translation table on f5, it will give reply to particular client.
