When use static command map subnet, like, static (inside,dmz) 192.168.0.0 192.168.0.0 netmask 255.255.255.0, does have security issue with it? What is infected for security if disable NAT with static command?
Doing a no nat also creates a translation slot in the xlate table. For eg. consider the statement
Static (inside,outside) 10.10.10.1 10.10.10.1 netmask 255.255.255.255
The above statement will still have a translation slot and will undergo the NAT process which is required as per the PIX ASAlgoritim. The 10.10.10.1 if going from inside to outside will go AS IT IS.
sh xlate local 10.10.10.1 will show you something like this
local 10.10.10.1 Global 10.10.10.1
