SNMP

SNMP is used to remotely monitor the state of the network and collect information about

Internet traffic events and device status into a database. It is a troubleshooting and

management tool that uses UDP protocol on Port 161 to communicate between clients

and servers. For example, SNMP can be used to monitor the amount of traffic passing

through the network.

Port Forwarding

Port Forwarding allows you to provide local services (for example, web hosting) for users

on the Internet or to play Internet games. When users send this type of request to your

network via the Internet, the iConnect625W router forwards these requests to the

appropriate computer. Hence, it allows you to direct incoming traffic to specific LAN hosts

based on a protocol port number and protocol.

Port Forwarding can be used with dynamic DHCP-assigned addresses and is

configurable per LAN group. For example, if you were configuring a Netmeeting server,

you would want to assign this server to a static IP address so that the IP address is not

re-assigned.

If Internet users are trying to access an Internet application, they must use the WAN IP

address. Port Forwarding translates the WAN IP address into a LAN IP address.

Before Port Forwarding can be configured, you must ensure that you have a LAN IP

Address configured in

LAN Clients

To configure Port Forwarding, follow the steps below.

Step 1

From the

Advanced

tab, click the

Port Forwarding

link on the left menu. The

following page appears:

Step 2:

From the

WAN Connection

drop-down list, select the connection type for

which you wish to which port forwarding is applied.

Step 3:

Check the

Allow Incoming Ping

(ICMP) checkbox if you wish to monitor the

connectivity between the IP devices. This is optional.

Step 4:

From the

Select LAN Group

drop-down list,

LAN group 1

is the default setting

that was previously configured under

Setup>LAN Configuration.

Step 5:

For the

LAN IP

drop-down list, select the IP address for which you

Page 75 / 181

iConnect625W ADSL/ADSL2+ Router User Guide

wish to host the service.

It is recommended that the Static IP Addresses rather than the DHCP IP

Addresses be used for Port Forwarding.

Step 6:

If you wish to add a new LAN IP address, click the

New IP

button. The

LAN

Clients

page appears:

Step 7:

Follow the instructions under the

LAN Clients

section for details on entering

the fields.

Step 8:

To add a new rule for this connection, highlight the appropriate category radio

button for your configuration in the
