"Deployment Modes Overview"
Caching Port Numbers — The Caching Port Numbers are the ports
I
on which the Webcache will listen for traffic. The default number is
8080 for Proxy Cache mode and 80 for Transparent and Inline Cache
modes.
The following sections explain certain key concepts of configuring your
network, which you must understand in order to set up the Webcache
successfully.
To operate correctly, each device on your network (for example a
webcache or management station) must have a unique IP address. IP
addresses have the format nnn.nnn.nnn.nnn where n is a decimal
number between 0 and 255. An example IP address is '192.168.100.8'
with a subnet mask of 255.255.255.0.
The IP address can be split into two parts:
The first part ('192.168.100' in the example) identifies the network on
I
which the device resides.
The second part ('8' in the example) identifies the device within the
I
network.
If your network is internal to your organization only, you may use any
arbitrary IP address. We suggest you use addresses in the series
192.168.100.X (where X is a number between 1 and 254) with a subnet
mask of 255.255.255.0.
