Your rule will now appear in the Inbound Services table of the Rules menu (see Figure 4-10). This rule is different from a normal inbound port forwarding rule in that the Destination box contains an IP Address other than your normal WAN IP Address.

Figure 4-10

To test the connection from a PC on the Internet, enter http://<IP_address>, where <IP_address> is the public IP address you have mapped to your Web server. You should see the home page of your Web server.

Inbound Rule Example: Exposed Host

Specifying an exposed host allows you to set up a computer or server that is available to anyone on the Internet for services that you haven't defined.

To expose one of the PCs on your LAN as this host (see Figure 4-11):

1.Create an inbound rule that allows all protocols.

2.Place the rule below all other inbound rules by the clicking the Down icon adjacent to the rule.

Note: For security, NETGEAR strongly recommends that you avoid creating an exposed host. When a computer is designated as the exposed host, it loses

much of the protection of the firewall and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network.
