I have a list of address and port that I want to block people from accessing
them in this computer, such as port 1200 and IP 207.73.177.130.
Is there a possible way to do it without installing 3rd party firewall?

Im using windows xp pro.

Thanks

You would have to enable the Internet Connection
Firewall. Once enabled, you can adjust ports, as noted
below on URL http://support.microsoft.com/default.aspx?

How to Manually Open Ports in Internet Connection
Firewall in Windows XP

SUMMARY
This article describes how to manually open ports in
Internet Connection Firewall (ICF) in Windows XP.
MORE INFORMATION
Programs may potentially require ports to be manually
opened so that the programs work correctly when ICF is in
use either on the local computer or on the gateway
computer. You may have to use this procedure if there is
a service that is running on a computer that has ICF
enabled that you want to make available to users on the
Internet.

Note The actual port settings vary from program to
program.

To manually open a port:
Click Start, and then click My Network Places.
Under Network Tasks, click View Network Connections. (Or,
you can right-click My Network Places on the desktop, and
then click Properties.)
Right-click the connection that you use for the Internet,
and then click Properties.
Click the Advanced tab, and then click Settings.

Note If the Settings button is unavailable, ICF is not
enabled on this connection and you do not have to open
any ports (they are all already open).
Click Add to open a new port.
In the Description box, type a friendly name. For
example, type File Sharing : Port 445.
In the Name or IP address of the computer hosting this
service on your network box, type 127.0.0.1.

NOTE: You can specify the IP address of an internal
computer; however, in most cases, you use 127.0.0.1.
In the External port and Internal port boxes, type the
port number. In most cases, this number is the same.
Click either TCP or UDP, and then click OK.
Repeat this process for each port to be opened.
For additional information about some applications and
games that may require you to manually open the ports so
that the programs can work correctly, and for information
about which inbound ports to open, visit the following
