Hi , Basically we have 3

Hi ,

 

Basically we have 3 modes of NAT on this new version:  AUTO-NAT , MANUAL NAT and AFTER AUTO NAT.

They have  different priority on the ASA

 

Here are some examples :

 

Auto-NAT

1.Create the object to identify the IP

 

Object network webserver

Host 192.168.1.88

 

2.Create the NAT entry inside the object

Syntaxis

NAT (int name , int name)  # source static/dynamic  (object name source ) (object name destination )

 

Object network my_internal_net

Subnet 192.168.10.0 255.255.255.0

Nat (in,out) 2 source dynamic (object name )

 

Example of Dynamic-PAT

 

Object network inside-hosts

Subnet 192.168.1.0 255.255.255.0

Nat (in,out) 1 source dynamic interface

 

Static NAT to ANY

Object network inside-server

Host 192.168.1.99

Object network inside-server-global

Host 14.36.103.222

Nat (inside,any) static inside-server inside-server-global

 

 

Manual NAT with NAT 0

 

It’s created in the global mode, not inside an object

 

object network inside-net

 subnet 192.168.1.0 255.255.255.0

object network VPNhosts

 subnet 10.10.1.0 255.255.255.0

 

Nat (inside,outside) source dynamic inside-net interface destination static VPNhost VPNhost

 

AFTER-AUTO

Just add the keyword after-out to the sentence.

 

NAT (any,out) after-auto 1 source dynamic net_in net_out

 

Hope this help!
