Allowing Inbound Connections To Your Network

By default, the WNR834B router blocks any inbound traffic from the Internet to your computers
except for replies to your outbound traffic. However, you may need to create exceptions to this rule
for the following purposes:
• To allow remote computers on the Internet to access a server on your local network.
• To allow certain applications and games to work properly when their replies are not
recognized by your router.
Your router provides two features for creating these exceptions: Port Forwarding and Port
Triggering. This section explains how a normal outbound connection works, followed by two
examples explaining how Port Forwarding and Port Triggering operate and how they differ.
