LABEL

DESCRIPTION

Port Number

Assign a port number for P2P downloads. You can select a number from 2 to 65536. It

 

is recommended to use a port number greater than 1025.

 

 

DHT

Select Enable or Disable to use Distributed Hash Table (DHT) or not.

 

Note: When you use DHT, the NSA will also attempt to open a UDP port one number

 

smaller than the P2P download port number. So if the P2P download port number

 

is 9090, the NSA uses UDP port 9089.

 

 

Max. download rate

You may need to limit the bandwidth the NSA uses for P2P downloads if your network’s

 

other Internet applications are not getting enough downstream bandwidth. 0 has the

 

NSA impose no restriction.

 

 

Max. upload rate

You may need to limit the bandwidth the NSA uses to share files through P2P download

 

if your network’s other Internet applications are not getting enough upstream

 

bandwidth. 0 has the NSA impose no restriction.

 

If you do not allow any uploads, (for example, you set a limit of 1 KB/s) you will not

 

have a good standing in the P2P download community.

 

Note: The settings for maximum download/upload rates would not affect peers accessing

 

the NSA from the same LAN.

 

 

Maximum Number

Specify how many simultaneous P2P downloads are allowed on the NSA. You can enter

of Active Torrents

a number from 1 to 10.

 

 

Maximum Number

Specify how many simultaneous seeds are allowed on the NSA. Enter a number from 1

of Seeding Jobs

to 10. This value cannot exceed the one you configured in the Maximum Number of

 

Active Torrents field.

 

 

Maximum Number

Specify how many active connections are allowed on the NSA. Enter a number from 1 to

of Active

500. This specifies the number of computers that can connect to the NSA to download

Connections

files being shared by the NSA.

 

 

Keep Sharing While

With P2P download, the NSA starts sharing a file while you are downloading it. Set how

 

long to continue sharing a file after the NSA finishes the download.

 

Select Upload/Download Ratio to keep sharing a file until the NSA has uploaded a

 

specific percent compared to the download.

 

Select Seeding Time to keep sharing a file for a specific number of minutes after the

 

download finishes.

 

Continuing to share a file helps other P2P download users finish downloading it. Sharing

 

out at least as much as you download helps keep you in good standing in the P2P

 

download community.

 

Enter -1 to share a file indefinitely. Leave both check boxes blank to have the NSA stop

 

sharing the file as soon as the download finishes.

 

If you select both options, the NSA keeps sharing a file until both conditions exceed the

 

values you configure. For example, you entered 150% in the Upload/Download Ratio

 

field and 120 minutes in the Seeding Time field. The NSA keeps sharing a file until it

 

has shared 1.5 times the size of the file and has passed 120 minutes.

 

 

Email notifications

Select whether or not to send emails to the email address configured for emailing log

 

reports (see Section 17.4.2 on page 311) when the NSA starts downloading the file,

 

seeding the file, and/or finishes downloading the file.
