Netgear FWG114Pv1 – Wireless Firewall with USB Print Server Guide D’Exploitation

Firewall Protection and Content Filtering

6-7

Follow these guidelines when setting up port forwarding inbound rules:

•

If your external IP address is assigned dynamically by your ISP, the IP address may change 
periodically as the DHCP lease expires. Consider using the Dyamic DNS feature in the 
Advanced menus so that external users can always find your network.

•

If the IP address of the local server computer is assigned by DHCP, it may change when the 
computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu 
to keep the computer’s IP address constant.

•

Local computers must access the local server using the local LAN address of the computer. 
Attempts by local computers to access the server using the external WAN IP address will fail.

Remember that allowing inbound services opens holes in your FWG114P Wireless Firewall/Print 
Server. Only enable those ports that are necessary for your network. Following are two application 
examples of inbound rules:

If you host a public Web server on your local network, you can define a rule to allow inbound Web 
(HTTP) requests from any outside IP address to the IP address of your Web server any time of day. 

Some home broadband accounts do not allow you to run any server processes 

(such as a Web or FTP server). Your ISP may check for servers and suspend your 
account if it discovers active servers at your location. If you are unsure, refer to the 
Acceptable Use Policy of your ISP.
