Hi Harshit,

Thanks a lot for the hint.  So I added this

+       service {
+           input {
+               service-set NATout;
+           }
+           output {
+               service-set NATout;
+           }
+       }
[edit interfaces]
+   sp-1/2/0 {
+       unit 0 {
+           family inet;
+       }
+   }
[edit services]
+   service-set NATout {
+       nat-rules goOUT;
+       interface-service {
+           service-interface sp-1/2/0;
+       }
+   }

The router seems doing some things after that, but I can I example
the nat table?  like show ip nat ... in cisco world.

Many thanks,

OS

You need to define a service-set (which can be applied
 on the physical interface) and use this rule in that
 service-set. See the following links:

es/html/service-set-config4.html#1032529

thx

Hi,

I'm looking for a nat configuration example in juniper M7i.  I follow
the book setup the
service:

nat {
    pool OUTIP {
        address 10.1.2.3/32;
        port automatic;
    }
    rule goOUT {
        match-direction output;
        term 1 {
            from {
                destination-address {
                    10.10.10.10/32;
                }
            }
            then {
                translated {
                    source-pool OUTIP;
                    translation-type source dynamic;
                }
            }
        }
    }
}
How do I apply the nat service to a interface (I failed to find the
example from the book)?  
The router is
Model: m7i
JUNOS Base OS boot [8.0R2.8]
JUNOS Base OS Software Suite [8.0R2.8]
JUNOS Kernel Software Suite [8.0R2.8]
JUNOS Packet Forwarding Engine Support (M7i/M10i) [8.0R2.8]
JUNOS Routing Software Suite [8.0R2.8]
JUNOS Online Documentation [8.0R2.8]

Basically, I would like all packets from interface fe-0/0/0.0 go to
server 
10.10.10.10 be nat-ed.

=> [all other interfaces M7i  fe-0/0/0.0] --> 10.10.10.10 where
fe-0/0/0.0 has IP 10.1.2.1/24

Thanks a lot,

OS
