Static nat

jgeier
Hello,

how to establish a static Net Addres Translation?

For example the PUBLIC Address 192.168.0.2 should communicate to this PRIVATE adress 10.0.11.30.

And this PRIVATE Adress 10.0.11.30 should communicate with any other Internet hosts throug the PUBLIC Address 192.168.0.2

I have no idea how to do this.

Kind Regards
Jens Geier

    Hi, you need BOTH a DNAT (for incoming traffic) and an SNAT (for outgoing traffic).

    e.g.
    DNAT
    source: any
    dest: EXT IP (192.168.0.2 in your example)
    service: any
    change dest to: 10.0.11.30

    SNAT
    source: 10.0.11.30
    dest: any
    service: any
    change SOURCE to: EXT IP (192.168.0.2 in your example)
