    Hi everyone,

     

     It is possible to nat one source private IP address to many source public IP address?

     I have proxy server with private IP and I would like to nat this IP to many (pool) public IP. Is it possibly? 

     

    Thanks in advance.

    We can do that. As per below rule 1.1.1.1 can get SNAT to 4.4.4.4/8.8.8.8/12.12.12.12


    [edit]

    root@SRX# show security nat

    source {

    pool Multiple-Public-IP {

    address {

    4.4.4.4/32;

    8.8.8.8/32;

    12.12.12.12/32;

    }

    }

    rule-set 1-pvt-to-many-public {

    from zone trust;

    to zone untrust;

    rule test {

    match {

    source-address 1.1.1.1/32;

    }

    then {

    source-nat {

    pool {

    Multiple-Public-IP;

    }

    }

    }

    }

    }

    }



    [edit]

    root@SRX# show security nat | display set

    set security nat source pool Multiple-Public-IP address 4.4.4.4/32

    set security nat source pool Multiple-Public-IP address 8.8.8.8/32

    set security nat source pool Multiple-Public-IP address 12.12.12.12/32

    set security nat source rule-set 1-pvt-to-many-public from zone trust

    set security nat source rule-set 1-pvt-to-many-public to zone untrust

    set security nat source rule-set 1-pvt-to-many-public rule test match source-address 1.1.1.1/32

    set security nat source rule-set 1-pvt-to-many-public rule test then source-nat pool Multiple-Public-IP
