of the service applications that you want to provide on your LAN stations use TCP or UDP
protocols. If an application does, then you must configure a pinhole to implement port for-
warding. This is accessed from the Advanced -> Pinholes page.

Example: A LAN Requiring Three Pinholes .

pages describes how you set up your NAT-enabled Netopia Gateway to support three sepa-
rate applications. This requires passing three kinds of specific IP traffic through to your
LAN.
Application 1 : You have a Web server located on your LAN behind your Netopia Gateway
and would like users on the Internet to have access to it. With NAT "On", the only externally
visible IP address on your network is the Gateway's WAN IP (supplied by your Service Pro-
vider). All traffic intended for that LAN Web server must be directed to that IP address.
Application 2 : You want one of your LAN stations to act as the "central repository" for all
email for all of the LAN users.
Application 3 : One of your LAN stations is specially configured for game applications. You
want this specific LAN station to be dedicated to games.
A sample table to plan the desired pinholes is:
WAN Traffic Type
Web
Email
Games
For this example, Internet protocols TCP and UDP must be passed through the NAT security
feature and the Gateway's embedded Web (HTTP) port must be re-assigned by configuring
new settings on the Internal Servers page.
