Deployment Topologies
This section discusses the following types of deployment topologies:
2-4
• Single network segment
• Multiple network segments
Deploying in a Single Network Segment
In figure 2-3 on page 2-4, the network devices all belong in one network segment. All
devices, including clients have Class A IP addresses. The core switch is the default
gateway of the clients. The router is the default gateway of the core switch and the
appliance.
Note: If the appliance is not deployed between the router and the core switch, the
connection will go through the core switch and then to its default gateway, which
is the router. In return, the router redirects traffic to the intended server, thus
bypassing the appliance altogether.
