Figure 21 Virtual Server with Three Real Servers
22.3.2 Load Balancing Example 2
You have two internal networks, LAN 1 and LAN 2, that are restricted from accessing each other (Figure
22 on page 198). LAN 2 hosts two duplicate SMTP mail servers. You want clients on LAN 1 to be able to
access the SMTP servers on LAN 2.
You create a virtual server load balancing rule using IP address 10.0.1.100 and port 25, and add two
SMTP servers from LAN 2 to the rule. Now clients on LAN 1 can access the virtual server’s SMTP service by
connecting to 10.0.1.100 port 25. Clients see a single mail server.
