Replace IP's in Firewall Config for DR



  • I have multiple lines in my firewall configuration that have our IP NAT’ing configuration in them.
    When we go to our DR site and do a restore we will have a different range of external IP’s such as 66.###.###.#01-128
    nat (inside,outside) static 1##.###.###.#01 dns
    nat (inside,outside) static 1##.###.###.#02 dns
    nat (inside,outside) static 1##.###.###.#03 dns

    Is there a way of me doing a find and replace for multiple IP’sw with Multiple IP’s?
    Maybe with a spreadsheet or something by the way I see as my example above that they may use the same ending numbers and just do a find and replace with the beginning numbers but that isn’t the case.
    it would be 60 numbers between 129-255
    and 66-128 or something along those lines, wouldn’t know until I got to the DR site.



  • Hello @Donald-Hickman,

    I don’t know of an internal npp way to do this but if you can install python script plugin
    I assume we can find a solution doing it. If you want to go this way, please install python script
    plugin from the msi instead of using plugin manager.

    Cheers
