  • 1.  Destination NAT

    Posted 12-04-2012 00:08

    Dears,

     

    I have a J4350 with Junos 10.0 , which i planning to place as a  Internet router, I have only 1 public ip (1.1.1.1) which will be configured on the ethernet interface facing to ISP.

     

    I want to achieve the following:

     

    • I want all internal user to go on the internet by the public IP (1.1.1.1) configured on the router interface (nat overloading concept from cisco)
    • I want 4 internal servers, http,smtp,etc,etc to be publish on the internet by the same public IP 1.1.1.1 (port redirection concept of cisco)

    Is it possible by only 1 public IP

    A logic says it should be same becz the operating system are same ,waiting for Experts confirmation.

    Hello,

    Yes, destination NAT is configured in the same way on SRX and J-series.

    You can refer to following doc for examples

    Whave published a Network Configuration Example (NCE) titled:

    Junos OS NAT Configuration Examples for ScreenOS Users

     

    http://www.juniper.net/techpubs/en_US/junos12.2/information-products/topic-collections/nce/nat-configuration-for-screenos-users/nat-configuration-examples-for-screenos-users.pdf

     

    This NCE describes how to configure the Network Address Translation (NAT) functionality on Juniper Networks® SRX Series or J Series devices using the Junos® operating system (Junos OS) command-line interface (CLI). It will help ScreenOS users to migrate ScreenOS® Software on an SSG 300M-series or SSG 500M-series security device to Junos OS Software on an SRX Series Services Gateway or J Series Services Router.
