Packet Filtering

Packet Filtering confi gures advanced
public services on your local network,
such as web servers, FTP servers,
email servers, gaming servers or oth-
er specialized Internet services that
require delivery of specifi c requests
through the router to the appropriate
local network device for delivering
specifi c appication requests.
When unique requests for a particular
response are delivered to your router
via the Internet, the router will forward those requests to the designated local network device for via the Internet, the router will forward those requests to the designated local network device for
appropriate response.
Because when DHCP is in use, IP Addresses could change for a client device over time, it is best
practice to assign local network devices that have packet fi ltering rules assigned to them to use a
fi xed IP Address to prevent failures due to a change in IP Address that the packet fi lter does not
acknowledge.
