The following table provides a description of the pages available from within the Advanced Settings section of the Setup page.

Field Name

Description

Options

Use this page to enable or disable advanced

 

features on your network

 

 

IP Address Filtering

Use this page to configure IP address filters. These

 

filters prevent designated IP addresses from

 

accessing the Internet

 

 

MAC Address Filtering

Use this page to configure MAC address filters.

 

These filters prevent designated MAC addresses

 

from accessing the Internet

 

 

Port Filtering

Use this page to configure transmission control

 

protocol (TCP) and user datagram protocol (UDP)

 

port filters. These filters prevent a range of

 

TCP/UDP ports from accessing the Internet

 

 

Port Forwarding

Use this page to configure port forwarding for

 

local IP addresses. Port forwarding allows you to

 

run a server on the local area network (LAN) by

 

specifying the mapping of TCP/UDP ports to

 

local PCs or to the IP address of other devices.

 

This is a static setting that holds the ports open at

 

all times

 

 

Port Triggers

Use this page to configure TCP/UDP port

 

triggers. Port triggering is similar to port

 

forwarding, but is a dynamic function. In other

 

words, the ports are not held open, and the ports

 

close if no outgoing data is detected on the

 

selected ports for a period of 10 minutes
