Port Forwarding and Port Triggering Linksys EA-Series
To set up port range forwarding:
1. Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2. Set up a DHCP reservation for the IP address of the computer on which
you installed the software. (See “Configuration du serveur DHCP de votre
routeur” on page 39). In this example, the IP address of the desktop
computer with BitTorrent installed is 192.168.1.140.
3. Under Router Settings, click Security.
4. Click the Apps and Gaming tab.
5. Click Port Range Forwarding. The Port Range Forwarding screen opens.
6. Click Add a new Port Range Forwarding.
7. In the Application name field, enter a descriptive name.
8. In the Start ~ End Port fields, enter the range or ports. In this example,
the range is 6881 to 6889.
9. Select TCP as the protocol.
10. In the To IP Address field, enter the last 3 digits of the IP address of the
device running the software. The rest of the IP address fields already
completed. In this example, you would enter 140.
11. Select Enabled, then click Save. If you don’t want to use port range
forwarding but want to keep the information in the table, unselect the
checkbox.
TIPS
To use software like BitTorrent on multiple computers on your
network, create additional entries with a unique range of ports as
shown above. BitTorrent works only with ports between 6881 and
6999.
Depending on your computer’s firewall software, you may need to
open a range of ports in your firewall to enable software that uses
port range forwarding.
How to set up port range triggering for
online gaming
Why would I use port triggering instead of port forwarding? Port range
triggering allows the router to watch outgoing data for specific port numbers.
The IP address of the computer that sends the matching data is remembered
by the router, so that when the requested data returns through the router,
the data is routed back to the proper computer. An example of port range
triggering would be to enable a USB or Bluetooth headset for online chat and
gaming.
To set up port range triggering for multiple entries:
1. See your device documentation for information on the ports that the
device uses.
2. Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
