Networking  Firewall (can only be accessed by administrator)
The “CPE Access Control” section of this page gives users the ability to allow
or deny web/telnet access from WAN. By enabling and identifying a DMZ host, an
external attacker only has access to the DMZ host, rather than the entire private
network at the CPE’s back end. Furthermore, the redirection of ICMP can also be
enabled. The “Firewall Filter” section of this page is used to filter incoming network
traffic based on MAC, IP, protocol, TCP/UDP port and interface. Please refer to
Figure 2-16 and Figure 2-17 for more details. After setting the configurations of these
fields, press the “Apply” button to write the new configurations into the CPE and
press “Reboot” as shown in Figure 2-35, to reboot the system in order for the new
configurations to take effect.
