Junos OS

hello guys, i had this config below I just try it by hand but please correct me if I am wrong:

Screen OS config below:
set interface ethernet1 ip 192.168.15.254/24
set interface ethernet1 nat

SRX: (i'm not sure whether this is the correct translation for the above code)
set rule-set rs1 from zone trust
set rule-set rs1 to zone untrust
set rule-set rs1 rule r1 match source-address 0.0.0.0/0
set rule-set rs1 rule r1 match destination-address 0.0.0.0/0
set rule-set rs1 rule r1 then source-nat interface

set policy internet-access match source-address any destination-address any application any
set policy internet-access then permit

Any input is greatly appreciated?

Is there a JunOS simulator that can be downloaded?

Thanks.

Hello ,

The configuration is correct for interface based source NAT .  

For Simulators please check  : http://www.juniper.net/us/en/products-services/nos/junosphere/

Hello ,

To add to the above , the policy configuration should look like :

set security policies from-zone trust to-zone untrust policy internet-access match source-address any
set security policies from-zone trust to-zone untrust policy internet-access match destination-address ant
set security policies from-zone trust to-zone untrust policy internet-access match application any

set security policies from-zone trust to-zone untrust policy internet-access  then permit

For the NAT rule you don't need the destination term but it won't hurt either.

On the policy you are missing the zone designations.

set security policies from-zone trust to-zone untrust policy trust-to-untrust match source-address any
set security policies from-zone trust to-zone untrust policy trust-to-untrust match destination-address any
set security policies from-zone trust to-zone untrust policy trust-to-untrust match application any
set security policies from-zone trust to-zone untrust policy trust-to-untrust then permit

There is no simulator.  But there is a virual SRX you can request a demo download and use. 

Thank you guys for your valuable input..

JunOS has a lot of features that why needs a lot of typing..  🙂
