Dear All,
I was reading my NAT Design Paper, because I am going to Implement NAT in My Company.
Now, I want to ask you for only the Process of Static NAT , to allow External Users ? on internet side ? to ? access a specific server inside my LAN.
Which is the things that determine this NAT will Work from External to Internal , or Internal to External ?
Please answer the 3 questions .
1- Is it the Route command that I configured on the router it self , only ?
Or,
2- Is it the Route Command + NAT Table which is configured on the Router it self ?
Because As far as I know, I understood the following:-
To configure the NAT, I have to:-
1- determine which INTERFACE will act as IP NAT OUTSIDE , usually the one which have the IP from the ISP Side.
2- Determine which INTERFACE will act as IP NAT INSIDE , usually the one which have the IP from the Private LAN.
3- Determine the NAT statement , if its STATIC / dynamic /overloading .
4- Determine the Route command .
3- Here is Step 4 , I can make rule to forward every thing from INTERNAL to EXTERNAL or from EXTERNAL to INTERNAL , according to My Design Requirements.
So, from the NAT Command + Route Command , I can make the NAT From External to Internal , or, from Internal to External . is that correct ?
