Dynamic DNS makes it much easier to access a server from the Internet because you
can enter the name in the web browser. Otherwise, you must know the IP address
that the ISP assigned, which typically changes.
Port triggering for services and applications
[router mode]
If the AP is in router mode, port triggering can function as a dynamic extension of port
forwarding that is useful in these cases:
•
An application must use port forwarding to more than one local computer (but not
simultaneously).
•
An application must open incoming ports that are different from the outgoing port.
With port triggering, the AP monitors traffic to the Internet from an outbound “trigger”
port that you specify. For outbound traffic from that port, the AP saves the IP address
of the computer that sent the traffic. The AP temporarily opens the incoming port or
ports that you specify in your rule and forwards that incoming traffic to that destination.
Port forwarding creates a static mapping of a port number or range of ports to a single
local computer. Port triggering can dynamically open ports to any computer when
needed and close the ports when they are no longer needed.
Note: If you use applications such as multiplayer gaming, peer-to-peer connections,
real-time communications such as instant messaging, or remote assistance, we
recommend that you do not disable Universal Plug-N-Play (UPnP, see Improve network
connections with Universal Plug and Play [router mode] on page 110).
Note: The information in this section and subsections does not apply if the AP is in
access point mode.
Add a port triggering rule [router mode]
The AP does not provide default services and applications for port triggering rules. You
must define a custom service or application for each port triggering rule. The AP must
be in router mode.
To add a port triggering rule:
1. Launch a web browser from a computer or mobile device that is connected to a WiFi
network or LAN port on the AP.
2. Enter http://www.routerlogin.net in the address field.
