Setup Port Forwarding
(XBOX example)
1.
To setup Port Forwarding, use the following procedure:
2.
Access the web interface. Refer to
page 1
if needed. Click the
Gateway
link from the top of the screen. Click
Forwarding
from the
left side of the screen.
The screen example below shows how to setup an XBOX running
Modern Warfare
2. However, the same logic can apply to other
hosts/applications/services. Since multiple ports are used for XBOX
and this particular game, a separate forwarding rule is setup for each
port. Multiple ports and forwarding rules may not be the case for other
applications, however.
The XBOX IP is entered in the Local IP field. Notice how the IP is
entered in 4 rows, one row for each port used by the XBOX.
The ports used by the XBOX are defined in the Internal Port field.
The same ports used by the XBOX are also defined in the External
Port Start and End fields. This configuration now allows the XBOX
to receive data from the internet on all possible XBOX ports.
Keep in mind that you may want an application/service to listen on
one port, while external internet users who want to access that
application address it using another port. Using the screen
example below,
Internal Ports
are the ports that local servers
listen to.
External Ports
are the ports that the cable modem listens
to from the WAN. In summary, when you have port forwarding
rules set up, your cable modem takes incoming data off of the
external IP address:port number and sends that data to an internal
IP address:port number
(Local IP
). Port Forwarding rules are
created per port. So a rule set up for port 53 will only work for port
53. A port can only be used by one program at a time.
