Trend Micro™ InterScan™ Gateway Security Appliance M-Series Deployment Guide

Deployment Topologies

This section discusses the following types of deployment topologies:

• Single network segment

• Multiple network segments

Deploying in a Single Network Segment

In figure 3-3 on page 3-4, the network devices all belong in one network segment. All

devices, including clients have Class A IP addresses. The core switch is the clients'

default gateway. The router is the core switch and the default gateway of the appli

ance.

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.
