Access Rule Example 3—Allowing
Inbound SMTP Traffic and Web Traffic
As discussed earlier in this chapter, NAT is used to translate public IP addresses to
private IP addresses and vice versa.This example explains how NAT is used to trans-
late SMTP and Web traffic that is received by a single public IP address to two dif-
ferent servers on the DMZ (see Figure 4.42).
Figure 4.42 Example 3—Network Diagram
First, you need to create the address objects.This can be accomplished with three
objects:
DMZ-SMTP-01—10.10.50.100
DMZ-WEB-01—10.10.50.101
WAN-SMTP_WEB—172.24.16.3
