Web server should appear.
LAN WAN Inbound Rule: Specifying an 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 have not yet defined.
To expose one of the PCs on your LAN as this host:
1. Create an inbound rule that allows all protocols.
2. Place the new rule below all other inbound rules.
Outbound Rules Example
Outbound rules let you prevent users from using applications such as Instant Messenger, Real
Audio, or other non-essential services.
LAN WAN Outbound Rule: Blocking Instant Messenger
To block Instant Messenger usage by employees during working hours, you can create an
outbound rule to block that application from any internal IP address to any external address
according to the schedule that you have created on the Schedule screen. See the example shown in
Figure 4-7 on page 4-15.
You can also have the VPN firewall log any attempt to use Instant Messenger during that blocked
period.
Note: For security, NETGEAR strongly recommends that you avoid creating an exposed
host. When a computer on your LAN 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.
