Performing Initial Software Configuration on the SRX3400 Services Gateway

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 Software 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#cli

    root#
  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-password

    New password: password

    Retype new password: password
  6. Configure an administrator account on the device. When prompted, enter the password for the administrator account.

    [edit]

    root@# set system login user admin class super-user authentication plain-text-password

    New password: password

    Retype new password: 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 IP address and prefix length for the device’s Ethernet interface.

    [edit]

    admin@# set interfaces fxp0 unit 0 family inet address address/prefix-length
  11. Configure the traffic interface.

    [edit]

    admin@# set interfaces ge-0/0/0 unit 0 family inet address address/prefix-length

    admin@# set interfaces ge-0/0/1 unit 0 family inet address address/prefix-length
  12. Configure the default route.

    [edit]

    admin@# set routing-options static route 0.0.0.0/0 next-hop gateway
  13. Configure basic security zones and bind them to traffic interfaces.

    [edit]

    admin@# set security zones security-zone trust interfaces ge-0/0/0

    admin@# set security zones security-zone untrust interfaces ge-0/0/1
  14. 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
  15. Check the configuration for validity.

    [edit]

    admin@# commit check

    configuration check succeeds
  16. Commit the configuration to activate it on the device.

    [edit]

    admin@# commit

    commit complete
  17. Optionally, display the configuration to verify that it is correct.
