I have a basic question , please answer it

What will happen if I put like given below in my ASA ?

nat (inside) 1 0 0

global (outside) 1 netmask

static (inside ,outside) netmask 255 0

Whether it means that from inside to outside my local IP will go as and from outside to inside it will be ? Is it correct , please let me know

its true if those commands are used separately but if you using both commands at same time static take precedence and host will go outside as (otherwise it would be asymmetric - outside host would start communication with and answer would come from - its not possible)


Hope that helps rate if it does

For the IP traffic going outside will be seen as source

Also traffic coming to the IP will be redirected to the IP , provided there is an Access-list allowing that traffic.

Static NAT will be more prferred.
