Pack 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 req 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

ﬁxed IP Address to prevent failures due to a change in IP Address that the packet ﬁ lter does not acknowledge.
