Figure 3-12 DMZ Examples
When the LAN has a DMZ/firewall server, you can enable DMZ on the CPE so that packets
from the WAN are forwarded to the firewall (Figure 3-13). Alternatively, you can enable
Internet Control Message Protocol (ICMP) redirect error messages to support Layer 2
multicast features.
