Windows
XP Service Pack 2 (SP2) includes a built-in Firewall. A
Firewall will filter or block information coming into your
computer or office network. The default configuration of
the Windows Firewall control panel in Windows XP SP2 can
prevent commonly used applications from functioning. To
re-enable this functionality, you can add the Program or
the Ports that a Program uses to the Firewall's Exceptions
list.
After
adding a program to the Exceptions list, the port will open
only when the program is being used and then close when
the program is shut down. By blocking these open ports at
times other than when you are actively using them, your
computer will maintain a higher degree of safety from malicious
attack. The more programs that get added to the Exceptions
list the weaker your level of security. To help decrease
your security risk, Microsoft offers these guidelines:
- Only
allow an exception when you really need it.
- Never
allow an exception for a program that you don't recognize.
- Remove
an exception when you no longer need it.
Common
programs in use within the College that may require use
of these ports include Cisco VPN Client, FileMaker Pro,
Macromedia Dreamweaver, NetMeeting and Palm HotSynch Manager.
Many Internet-enabled games and Instant Messaging programs
like AOL Instant Messenger and Yahoo Instant Messenger will
also be affected.
Please
be aware, the commonly used applications listed in this
How To (Cisco VPN, FileMaker Pro, Retrospect) need their
Ports opened. They do not need added to the Exceptions List
as a Program as well.

How
To Add a Program to
the Exceptions List
NOTE:
By default Windows Firewall will ask you if you want to add a
program to the exception list the first time you use the program.
You will see a message with three choices: Keep Blocking,
Unblock, or Ask Me Later.
Keep Blocking:
Adds the application to the Exceptions list but in a Disabled
state so that the ports are not opened. By adding the application
to the Exceptions list, Windows Firewall does not prompt you every
time the it is run.
Unblock:
Adds the application to the Exceptions list in an Enabled state
so that the ports are opened.
Ask Me Later:
Blocks unsolicited incoming traffic and does not add it to the
Exceptions list. You will be prompted again the next time the
application is run.
These are
the general steps to add a program to the Windows XP SP2 Firewall
Exceptions list. You should only do this for known, "safe"
applications.
- Click Start,
and then click Control Panel.
- Double-click
Windows Firewall (or click Security Center and
then Windows Firewall).
- In the
Windows Firewall control panel, click the Exceptions

- Restart
the computer to enable these choices.
NOTE: If you didn't see the name of a program you were
attempting to add above, click the Browse button. Then
click My Computer. Double Click on Local Disk (C:).
Programs are usually stored in the Program Files folder on your
computer, so Double Click on Program Files. You will
now need to locate and open the application's folder. Then select
the EXE file will open the application.

How
To Open Ports with a BAT file
NOTE:
ICT has created several "BAT" or Batch files that automate
the creation of the FileMaker Pro, IBIS printing, Retrospect,
and VPN ports. You will download a self extracting archive file
that will expand to a folder containing six BAT files.
- Click the
BAT_file.exe
link and choose to Save the file to the computer. Ex:
Save to the Desktop.
- Once the
file downloads, double-click on the downloaded BAT_files.exe
file.
- Click OK.
- Open the
Bat_files folder. You will see these files:
Open_2_VPN_FMP_NoPrompt.bat
The file will open the ports for VPN and FileMaker Pro without
stopping.
Open_All5_SP2ports_NoPrompt.bat
The file will open the ports for FileMaker Pro, IBIS, QTSS,
Retrospect and VPN without stopping.
Open_All5_SP2ports_Prompt.bat
The file will pause and prompt you to open the ports for each
of the five applications.
Open_FMP_SP2_ports.bat
This file will pause and prompt you to open the FileMaker Pro
ports.
Open_IBIS_SP2_port.bat
This file will pause and prompt you to open the LPR Print Ports
for IBIS Printing port.
Open_QTSS_SP2_ports.bat
This file will pause and prompt you to open the QuickTime Streaming
Server ports.
Open_Retrospect_SP2_ports.bat
This file will pause and prompt you to open the Retrospect ports.
Open_VPN_SP2_ports.bat
This file will pause and prompt you to open the VPN ports.
NOTE: The "no prompt" file will simply open
a command windows and run. When finished, the command window
will close. The remaining BAT files will pause. You will have
a choice or pressing 1 or 2. The "1"
choice will execute the command. The "2" choice will
cancel the command.
