Cisco ASA Static NAT Creator

This program will create a static 1 to 1 NAT for Cisco ASA 8.4.2+ code.

The format needed for the conversion to work is:
[Real interface] [Mapped Interface] [Real IP] [Mapped IP]

Example:
INSIDE OUTSIDE 192.168.5.5 55.55.55.5

Input NAT Requirements: INSIDE OUTSIDE 192.168.1.2 55.55.55.2 INSIDE OUTSIDE 192.168.1.3 55.55.55.3 INSIDE OUTSIDE 192.168.1.4 55.55.55.4

About Static NAT

Static NAT provides a one-to-one mapping between real and mapped IP addresses. This tool generates the proper configuration syntax for Cisco ASA firewalls running version 8.4.2 and later, which uses the newer NAT configuration format.

Input Format

Each line should contain four elements separated by spaces:

1. Real Interface - The interface where the real IP address resides (e.g., INSIDE)
2. Mapped Interface - The interface where the mapped IP address will be used (e.g., OUTSIDE)
3. Real IP - The actual IP address of the host
4. Mapped IP - The translated IP address
