4.4.4 Port Filtering
The Port Filtering page allows you to enter ranges of destination ports
(applications) that you don’t want your LAN PCs to send packets to. Any
packets your LAN PCs send to these destination ports will be blocked. For
example, you could block access to worldwide web browsing (HTTP port 80)
but still allow email service (SMTP port 25 and POP3 port 110).
To enable port filtering, enter the Start port and End port for each range.
Then select its protocol form the drop-down list and check the Enable box,
and click Apply button. To block only one port, set both Start and End ports
the same.
4.4.5 Forwarding
For communications between LAN and WAN, the CBV3843Z4S normally only
allows you to originate an IP connection with a PC on the WAN; it will ignore
attempts of the WAN PC to originate a connection onto your PC. This protects
you from malicious attacks from outsiders. However, sometimes you may wish
for anyone outside to be able to originate a connection to a particular PC on
your LAN if the destination port (application) matches one you specify.
The Forwarding page allows you to specify up to 10 rules.
CBV3843Z4S Cable Modem
User’s Manual
13
Using the Port Forwarding page, you can provide local services (web servers,
FTP servers, mail servers, etc) for people on the Internet or play Internet
games. A table of commonly used port numbers is also provided.
4.4.6 Port Triggers
The Port Triggers page allows you to configure dynamic triggers to specific
devices on the LAN. This allows for special applications that require specific
port numbers with bi-directional traffic to function properly. Applications such
as video conferencing, voice, gaming, and some messenging program
features may require these special settings.
Port Triggering is an elegant mechanism that does the forwarding for you,
each time you play the game.
You can specify up to 10 port ranges on which to trigger.
CBV3843Z4S Cable Modem
User’s Manual
14
4.4.7 DMZ Host
The DMZ page allows you to configure a specific network device to be
exposed or visible directly to the WAN (public Internet). Setting a host on your
local network as demilitarized zone (DMZ) forwards any network traffic that is
not redirected to another host via the port forwarding feature to the IP address
of the host (PC). This designates one PC on your LAN that should be left
accessible to all PCs from the WAN side for all ports. For example, if you
locate a HTTP server on this machine, anyone will be able to access that
HTTP server by using your CBV3843Z4S ’s IP address as the destination.
This may be used when problem applications do not work with port triggers.
The setting of “0” indicates NO DMZ PC.
