Note: You need to
enable L2 mode on the NetScaler appliance for transparent SSL acceleration to
acceleration is useful for running multiple applications on a secure server
with the same public IP, and also for SSL acceleration without using an
additional public IP.
In a transparent
SSL acceleration setup, the NetScaler appliance is transparent to the client,
because the IP address at which the appliance receives requests is the same as
the Web server's IP address.
offloads SSL traffic processing from the Web server and sends either clear text
or encrypted traffic (depending on the configuration) to the web server. All
other traffic is transparent to the NetScaler and is bridged to the Web server.
Therefore, other applications running on the server are unaffected.
There are three
modes of transparent SSL acceleration available on the NetScaler:
- Service-based transparent
access, where the service type can be SSL or SSL_TCP.
- Virtual server-based
transparent access with a wildcard IP address (*:443).
- SSL VIP-based transparent
access with end-to-end encryption.
Note: An SSL_TCP
service is used for non-HTTPS services (for example SMTPS and IMAPS).
