When using SSL Pass Through the communication between the the client and end server is encrypted and the BIG-IP can’t see good things like the HTTP Headers or data. The BIG-IP is limited to seeing only a few pieces of information, the source IP, the destination IP and the SSL Session ID. Mar 24, 2019 · The F5 can be configured to allow a TLS 1.0 connection and forward it as TLS 1.2 to servers behind the VIP.

One of the primary reasons for investing in an F5 is for the purpose of SSL Offloading, that is, converting external HTTPS traffic into normal HTTP traffic so that your web servers don't need to do the work themselves. Configured for SSL Passthrough (see step 1 below) VIP must listen on port 8443, and proxy back to all master hosts on port 8443.

The setup is fairly traditional- edge router to firewall to F5 to server. I have spoken with F5 who pointed me to this setting: Passthrough routes are a special case: to support those, it is necessary to write an iRule that parses the SNI ClientHello handshake record and looks up the servername in an F5 data-group. The router creates this iRule, associates the iRule with the vserver, and updates the F5 data-group as passthrough routes are created and deleted.
