P2P Download Security - ZyXEL Communications NAS326-2T User Manual

After your P2P download and sharing are finished, you can go to the incoming folder within the
destination share or folder and delete the .torrent file if you need to free up hard disk space.

14.5.2 P2P Download Security

When you download using P2P, you reveal your IP address. This increases the risk of hacking attacks,
which can be protected against by a good firewall.
Use a Hardware-based Firewall
Place a hardware-based firewall between your network and the Internet (a software-based firewall on
your computer would just protect the computer itself, not the NAS since your computer is not between
your NAS and the Internet).
Figure 197 Firewall
Ideally your firewall should have the following:
• Stateful packet inspection to control access between the Internet and your network and protect your
NAS (and computers) from hacking attacks.
• IDP (Intrusion Detection and Prevention) to detect malicious packets within normal network traffic
and take immediate action against them.
• Anti-virus to check files you download for computer viruses.
P2P Download and Your Firewall
The anti-virus feature on a firewall probably cannot check P2P downloads for viruses, so use anti-virus
software on your computer to scan the NAS for viruses.
When you download using P2P download, many other P2P download users are also trying to download
the file from you. The firewall slows this down because by default, it only allows traffic from the Internet in
response to a request that originated on the LAN (it lets you get files from the Internet and blocks those
on the Internet from getting files from you).
