UPnP

UPnP is a networking architecture that provides compatibility among networking

equipment, software and peripherals such as game consoles, digital cameras and other

systems that connect by TCP/IP. It can be supported on any operating system, and

boasts device-driver independence and zero-configuration networking.

UPnP is a standard that uses Internet and Web protocols to enable the iConnect625W to

plug into a network and automatically recognise each other. This feature is set to

Disabled

by default in the iConnect625W.

This feature requires one active WAN connection. In the presence of multiple WAN

connections, select a connection on which the incoming traffic is present, for example, the

default WAN connection.

Follow the steps below to enable

UPnP

.

Step 1

From the

Advanced

tab, click the

SNTP

SNTP ensures that the computer clock time can be synchronised in a network of

computers to the millisecond to the public SNTP servers. It uses the UDP protocol on port

123 to communicate between clients and servers.

When the SNTP feature is enabled, your iConnect625W starts verifying the time clock

information from the primary SNTP server. If it does not get a valid response within the

Timeout

period, it makes additional attempts based on the number on the value of the

Retry Count

field before it moves to the Secondary SNTP server. If there is no valid

response either for this server, it moves on to the Tertiary SNTP server. If it does not get a

valid response from all the servers, the program stops.

When it does receive a valid response from one of the servers, the program goes to sleep

for a few minutes as specified in the

Polling Interval

field before starting the whole process

again.

Follow the steps below to configure

SNTP.

Step 1

:

From the

Advanced

tab, click the

SNTP

link on the left menu. The following

page appears:

Step 2:

The following table lists the

SNTP

screen fields and their definitions:

Field

Description

Enable SNTP

Check this checkbox to enable the iConnect625W to

synchronise the system time to the public SNTP servers.

Primary SNTP Server

The IP address or the host name of the primary SNTP

server. Refer to your ISP for this information. The default

setting is

0.0.0.0

.

Secondary SNTP

Server

The IP address or host name of the secondary SNTP server.

Refer to your ISP for this information. The default setting is

0.0.0.0.

Tertiary SNTP Server

The IP address or host name of the tertiary SNTP server.

Refer to your ISP for this information. The default setting is

0.0.0.0.

Timeout

The time in seconds that the iConnect625W will wait for an

SNTP server to respond. If the router fails to connect to an

SNTP server within the timeout period, it retries the

connection. The default is set to

5

seconds.

Polling Interval

The amount of time (in minutes) that the iConnect625W

checks the time between a successful connection with an

SNTP server and a new attempt to connect to an SNTP

server. The default setting is

30

minutes.

Retry Count

The number of retries before a backup server is polled, i.e.

the number of times the router tries to connect to an SNTP

server before it tries to connect to the next server in line. The

default setting is set to

2

.

Time Zone

The time zone where the router resides.

Daylight

Select this option to enable daylight saving time (DST). DST
