The login timeout option allows you to set the period of time that you
can be logged into the Router's setup interface. The timer starts when
there is no activity. For example, you have made some changes in the
setup interface, then left your computer alone without clicking "Logout".
Assuming the timeout is set to 10 minutes, then 10 minutes after you
leave, the login session will expire. You will have to login to the router
again to make any more changes. The login timeout option is for security
purposes and the default is set to 10 minutes. As a note, only one
computer can be logged into the Router's advanced setup interface at
one time.
The Router keeps time by connecting to a Simple Network Time Protocol
(SNTP) server. This allows the Router to synchronize the system clock to
the Internet. The synchronized clock in the Router is used to record the
security log and control client filtering. Select the time zone that you
reside in. If you reside in an area that observes Daylight Saving, then place
a checkmark in the box next to "Enable Daylight Saving". The system
clock may not update immediately. Allow at least 15 minutes for the
router to contact the time servers on the Internet and get a response. You
cannot set the clock yourself.
You can specify which SNTP servers the Router will use to update it's
system clock, although doing this should only be necessary if if you are
experiencing difficulty.
Before you enable this function, make sure you have changed the
administrator password. Remote management allows you to make
changes to your Router's settings from anywhere on the Internet.
You can allow any PC on the Internet to remotely manage the Router, by
checking the Any IP address can remotely manage the router checkbox.
Alternatively, you can specify a single IP address that is allowed to
remotely manage the Router. This is more secure, as only the specified IP
address will be able to manage the Router.
Before you enable this function, make sure you have changed the
administrator password. Network Address Translation (NAT) is the
method by which the router shares the single IP address assigned by your
ISP with the computers on your network. This function should only be
used by advanced users, and if your ISP assigns you multiple IP addresses
or you need NAT disabled for an advanced system configuration. If you
