Protecting Your Network 3-7
v1.0, October 2008
Remember that allowing inbound services opens holes in your firewall. Enable only those ports
that are necessary for your network. Following are two application examples of inbound rules.
Inbound Rule Example: A Local Public Web Server
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 at any time of
day. An inbound rule is shown in the Inbound Services screen, which is accessible by clicking on
Add under Inbound Services in the Firewall Rules screen.
ote: Some residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP might
periodically check for servers and might suspend your account if it discovers any
active services at your location. If you are unsure, refer to the acceptable use policy
of your ISP.
