Performing Initial Software Configuration on the SRX220 Services Gateway Using the CLI

This procedure connects the device to the network but does not enable it to forward traffic. For complete information about enabling the device to forward traffic, including examples, see the appropriate Junos OS configuration guides.

To configure the software:

  1. Verify that the device is powered on.
  2. Log in as the root user. There is no password.
  3. Start the CLI.
    root@%cliroot>
  4. Enter configuration mode.
    configure [edit]root#
  5. Set the root authentication password by entering a cleartext password, an encrypted password, or an SSH public key string (DSA or RSA).
    [edit]root# set system root-authentication plain-text-passwordNew password: password Retype new password: password
  6. Configure an administrator account on the device.
    [edit]root# set system login user admin class super-user authentication plain-text-password
  7. Commit the configuration to activate it on the device.
    [edit]root# commit
  8. Log in as the administrative user you configured in Step 6.
  9. Configure the name of the device. If the name includes spaces, enclose the name in quotation marks (“ ”).
    configure [edit]admin# set system host-name host-name
  10. Configure the traffic interface.
    [edit]admin# set interfaces ge-0/0/1 unit 0 family inet address address/prefix-length
  11. Configure the default route.
    [edit]admin# set routing-options static route 0.0.0.0/0 next-hop gateway
  12. Configure basic security zones and bind them to traffic interfaces.
    [edit]admin# set security zones security-zone untrust interfaces ge-0/0/1
  13. Configure basic security policies.
    [edit]admin# set security policies from-zone trust to-zone untrust policy policy-name match source-address any destination-address any application any admin# set security policies from-zone trust to-zone untrust policy policy-name then permit
  14. Create a Network Address Translation (NAT) rule for source translation of all Internet-bound traffic.
    [edit]admin# set security nat source rule-set interface-nat from zone trust admin# set security nat source rule-set interface-nat to zone untrust admin# set security nat source rule-set interface-nat rule rule1 match source-address 0.0.0.0/0 destination-address 0.0.0.0/0admin# set security nat source rule-set interface-nat rule rule1 then source-nat interface
  15. Check the configuration for validity.
    [edit]admin# commit checkconfiguration check succeeds
  16. Commit the configuration to activate it on the device.
    [edit]admin# commitcommit complete
  17. Optionally, display the configuration to verify that it is correct.
    [edit]admin# showsystem {host-name devicea;domain-name lab.device.net;domain-search [ lab.device.net device.net ];backup-device 192.168.2.44;time-zone America/Los_Angeles;root-authentication {ssh-rsa "ssh-rsa AAAAB3Nza...D9Y2gXF9ac==root@devicea.lab.device.net";}name-server {10.148.2.32;}services {}ntp { server 10.148.2.21; }}interfaces {ge-0/0/0 {unit 0 {family inet {address 192.168.1.1/24;}}}lo0 {unit 0 {family inet {address 172.16.1.24/32;}}}}
  18. Optionally, configure additional properties by adding the necessary configuration statements. Then commit the changes to activate them on the services gateway.
    [edit]admin@device# commit
  19. When you have finished configuring the services gateway, exit configuration mode.
    [edit]admin@device# exitadmin@device>
