User's Manual

• POP3 (Post Office Protocol 3) A standard mail server commonly used on

the Internet. It provides a message store that holds incoming e-mail until

users log on and download it. POP3 is a simple system with little selectivity.

All pending messages and attachments are downloaded at the same time.

POP3 uses the SMTP messaging protocol.

• NNTP (Network News Transfer Protocol) The protocol used to connect to

Usenet groups on the Internet. Usenet newsreaders support the NNTP pro-

tocol.

• SNMP (Simple Network Management Protocol) A widely used network

monitoring and control protocol. Data is passed from SNMP agents, which

are hardware and/or software processes reporting activity in each network

device (hub, router, etc.) to the workstation console used to oversee the net-

work. The agents return information contained in a MIB (Management

Information Base), which is a data structure that defines what is obtainable

from the device and what can be controlled (turned off, on, etc.).

You must check the Enable box to enable the applications you have defined.

To add a server using UPnP Forwarding:

2. Next to the name of the application, enter the number of the external port

used by the server in the Ext. Port column. Check with the Internet appli-

cation software documentation for more information.

3. On the same line, select the protocol UDP or TCP.

4. Enter the number of the internal port used by the server in the Int. Port col-

umn. Check with the Internet application software documentation for more

information.

5. Enter the IP address of the server that you want the Internet users to be able

to access. To find the IP address, go to Appendix D: Finding the MAC

Address and IP Address for Your Ethernet Adapter.

6. Check the Enable box to enable the services you have defined. UPnP

Forwarding will not function if the Enable button is left unchecked. This is

disabled (unchecked) by default.
