gaming and videoconferencing. When using UPnP features, select Enable. Because allowing this may present a
risk to security, this feature is disabled by default. To allow users to make configuration changes, select Enabled.
To allow users to disable Internet access, select Enabled.

the radio button beside Enable. If you do not wish to have email alerts, click the radio button beside Disable.

Email address for alert logs. This is the email address where you would like the email alerts sent.
Return email address. Your mail server may require a return email address. Enter that here. If you're unsure as
to what address to enter, enter the same email address for Email address for alert logs.
Log. To access activity logs, select the Enable radio button. Click the Disable button to disable this function. With
logging enabled, you can choose to view temporary logs by clicking the Incoming Log button or Outgoing Log

Logviewer IP Address. For a permanent record of these logs, Logviewer software must be used. This software
is downloadable from the Linksys website, www.linksys.com. The Logviewer saves all incoming and outgoing
activity in a permanent file on your PC's hard drive. In the Logviewer IP Address field, enter the fixed IP address of
the PC running the Logviewer software. The Router will now send updated logs to that PC.
