How To Set Up Port Forwarding For A Range Of Ports - Linksys WRT1900AC Mode D'emploi

HOW TO SET UP PORT FORWARDING FOR A RANGE OF PORTS

Some applications require forwarding to a range of ports.
Example: You want to set up your computer so you can use BitTorrent, a popular
peer-to-peer file sharing application. BitTorrent uses port 6881 by default. If that
port is busy, the requesting BitTorrent client tries the next port in sequence. The
most common configuration for home routers with a single BitTorrent computer
is to set up port forwarding using a range of ports starting with 6881 and ending
with port 6889.
To set up port range forwarding, do the following:
• Log in to Linksys Smart Wi-Fi. (See "How to connect to Linksys Smart Wi-Fi" on
page 7.)
• Set up a DHCP reservation for the IP address of the computer on which you
installed the software. (See "How to set up the DHCP server on your router" on
page 27.) In this example, the IP address of the desktop computer with BitTorrent
installed is 192.168.1.140.
• Under Router Settings, click Security.
• Click the Apps and Gaming tab.
• Click Port Range Forwarding. The Port Range Forwarding screen opens.

• Click Add a new Port Range Forwarding.
• In the Application name field, enter a descriptive name.
• In the Start ~ End Port fields, enter the range or ports. In this example, the range
is "6881 – 6889".
• Select TCP as the protocol.
• In the Device IP# 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".
• Select Enabled, then click Save. If you don't want to use port range forwarding but
want to keep the information in the table, deselect 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
