PREPARING FOR DEPLOYMENT
CHAPTER 3: DEPLOYMENT 29
2. Does the network have an existing proxy?
If yes, it is recommended you deploy the Web Security appliance downstream from an
existing proxy server, meaning closer to the clients. The System Setup Wizard refers to this
as an upstream proxy configuration.
For more information, see “Using the Web Security Appliance in an Existing Proxy
Environment” on page 40.
3. Will you enable the L4 Traffic Monitor?
L4 Traffic Monitor deployment is independent of the Web Proxy deployment. You can
connect the L4 Traffic Monitor to a network tap or the mirror/span port of a switch.
For more information, see “Deploying the L4 Traffic Monitor” on page 41.
