Dynamic Domain Name Service (DDNS) is not anything new from the last decade. It associates a domain name to an IP address that changes over time. Users could access to the resources behind a dynamic IP address assigned CPE with an easily memorized domain name instead.
\nIn this post, I ll post the procedure of setting up DDNS at ScreenOS using NO-IP DDNS service with SSL enabled in GUI. One of ScreenOS’ beauties is the GUI management.
\n<\/p>\n

    \n
  1.  Go to: “Network” -> “DNS” -> “DDNS”<\/li>\n
  2.  Check “Config DDNS Client” and “Enable DDNS Client” and click “Apply”<\/li>\n
  3.  Click “New” button to setup a DDNS service.<\/li>\n
  4.  Fill in the blanks and it should be\n
      \n
    1. For server type: “dyndns”<\/li>\n
    2. Server name: “dynupdate.no-ip.com”<\/li>\n
    3. Refresh Interval: “3”<\/li>\n
    4. Minimum Update Interval: “60”<\/li>\n
    5. Clear text: “uncheck” (unchecking this option makes the DDNS update via https)<\/li>\n
    6. Username and Password: (input the one you have registered with at the NO-IP web site.)<\/li>\n
    7. Agent: “we could let the ScreenOS to fill in itself”<\/li>\n
    8. Bind to Interface: (select the WAN interface that is connecting to the internet.)<\/li>\n
    9. Host Name: (host name is the DDNS name you have registered at NO-IP web site.)<\/li>\n
    10. Service: “dyndns”<\/li>\n<\/ol>\n<\/li>\n
    11.  Click “OK” after finished.<\/li>\n
    12.  In this case, it should not work with the following error because the geotrust cert needs to be installed.\"Screenshot<\/a><\/li>\n
    13.  The Juniper web site has a guide of installing the Geotrust cert. The following URL from the official Juniper web page describes the procedure of the cert installation.ref: http:\/\/kb.juniper.net\/InfoCenter\/index?page=content&id=KB7380\n
        \n
      1. Download the cert: http:\/\/www.geotrust.com\/resources\/root_certificates\/certificates\/Equifax_Secure_Certificate_Authority_DER.cer<\/li>\n
      2. install the cert at GUI:\n
          \n
        1. Go to “Object” -> “Certificates”<\/li>\n
        2. click “Browse” to select the file.cer and click “Load”<\/li>\n<\/ol>\n<\/li>\n
        3. Once it is done, your Cert page should look like this.\"Screenshot<\/a><\/li>\n<\/ol>\n<\/li>\n
        4.  Now the DDNS update via HTTPS should update successfully with the “Last-response” of “Good” at “Network” -> “DNS” -> “DDNS” page.<\/li>\n<\/ol>\n

          To verify the DDNS with dynamic IP address association, logging back into the NO-IP website should have the record of the WAN IP address of the firewall bind to DDNS host address.<\/p>\n","protected":false},"excerpt":{"rendered":"
