Introduction<\/strong><\/h3>\n

The BigIP F5 provide 2 ways in which SSL is processed. These are :<\/p>\n

Client SSL<\/strong> – F5 decrypts the encrypted traffic inbound from the client.
Server SSL<\/strong> – Traffic is re-encrypted by the F5 then routed onto the backend servers.<\/p>\n

There are a number of advantages to SSL termination on the F5, which are :<\/p>\n

    \n
  1. Allows iRules processing and cookie persistence.<\/li>\n
  2. SSL Traffic offload from web servers<\/li>\n
  3. SSL key exchange and bulk encryption is performed by a single piece of BigIP F5 hardware rather then needing (to install) additional hardware in each webserver.<\/li>\n
  4. Centralized certificate management<\/li>\n<\/ol>\n

    Configuration<\/strong><\/h3>\n

    Client SSL<\/strong><\/h4>\n

    Configuring Client SSL comprises of 3 steps.<\/p>\n

      \n
    1. Import or generate the SSL certificate and Key<\/li>\n
    2. Configure the client ssl-client profile<\/li>\n
    3. Configure the Virtual Server<\/li>\n<\/ol>\n

      1a. Certificate (Import)<\/strong><\/p>\n

        \n
      1. Goto ‘Local Traffic | SSL Certificates | Import’.<\/li>\n
      2. Select Certificate as the Import Type.<\/li>\n
      3. Configure the Certificate Name.<\/li>\n
      4. Upload the certificate within the certificate source section.<\/li>\n
      5. Click Import.<\/li>\n<\/ol>\n

        Note :<\/strong><\/em> Certificates should be in either Base-64 encoded or PEM format.<\/p>\n

        1b. Certificate  (Generate)<\/strong><\/p>\n

          \n
        1. Go to ‘Local Traffic | SSL Certificates | Create’.<\/li>\n
        2. Within the General Properties section enter the name and then complete the Certificate Property fields.<\/li>\n
        3. Click finished.<\/li>\n<\/ol>\n

          Note :<\/strong> <\/strong><\/em>Certificates and keys are synchronized on redundant systems.
          Note :<\/strong><\/em> The locations for the certificate\/keys are:<\/p>\n

                            Certificates: \/config\/ssl\/ssl.cert
                            Keys:          \/config\/ssl\/ssl.key<\/p>\n

          <\/em>2. Configure Profile<\/strong><\/p>\n

          Next you will need to configure the client ssl-client profile.<\/p>\n

            \n
          1. Goto ‘Local Traffic | Profiles | SSL | Client | Create’<\/li>\n
          2. Within the General Properties enter the Name and select the Parent Profile as clientssl.<\/li>\n
          3. Within the Configuration section select the Certificate and Key.<\/li>\n
          4. Click Finished.<\/li>\n<\/ol>\n

            3. Configure the Virtual Server<\/strong><\/p>\n

              \n
            1. Within the necessary Virtual Server under SSL Profile (Client) select the previously created profile.<\/li>\n<\/ol>\n

              Server SSL<\/strong><\/h4>\n

              If Server SSL is required then select the serverssl profile from the SSL Profile (Server) dropdown menu from within the Virtual Server.<\/p>\n","protected":false},"excerpt":{"rendered":"
