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 688 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 688 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 .)
• 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 92.68..40.
• 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 “688 – 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 “40”.
• 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 688 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
