Impossible to get online - reading HTTP/HTTPS/FTP Firewall problem

I cannot get online and diagnosis to assess the problem.

The error I get indicates that it is a firewall problem; However, when I disabled my firewall and tried to connect, it still wouldn't let me.  I ran the diagnostic and received an error message that passport.com certificate is expired.  It is said that the system could not connect over HTTP/HTTPS and FTP (passive) was able to connect.  Help, please.  Thank you!

Sorry try this first...

You can change the behavior of the Internet Connection Firewall by turning on various ICMP options, such as allow an incoming echo request, allow incoming timestamp request, allow incoming router requestand Allow redirect. Brief description of these options appear on the ICMP tab

If your network uses Internet connection sharing to provide Internet access to multiple computers, it is recommended to activate the shared Internet connection on the Internet Connection Firewall. However, you can activate the shared Internet connection and Firewall Internet connection separately. It's a good idea to enable the ICF on the Internet connection on any Microsoft Windows XP computer that is connected directly to the Internet.

Internet Connection Firewall can also help protect a single computer connected to the Internet. If you have a single computer connected to the Internet with a cable modem, a DSL modem, or a dial-up modem, Internet Connection Firewall protects your Internet connection. Do not cut the ICF for virtual private network (VPN) connections because Internet Connection Firewall interferes with file sharing and other VPN functions.

Internal modem

To restart an internal modem, you must restart the computer. If you still experience network connectivity problems after you restart the computer, go to step 2. If you connect to the Internet using a router, there may be a problem with the configuration settings, and they must be updated. To determine if a network connectivity problem is caused by a bad configuration or a problem with the router, you can bypass the router and connect your computer directly to the modem.

Warning Connect your computer directly to the Internet may be left vulnerable to attacks. To protect the computer against attacks, make sure that a firewall is installed and that the firewall is enabled on your computer. To learn more about the Windows Firewall that is included in Windows Vista, see the "Windows Firewall" section.

Windows Firewall

Windows Vista includes a firewall, called Windows Firewall. By default, the Windows Firewall is enabled. However, you should always check that the Windows Firewall is turned on before you connect the computer to the Internet. To verify that Windows Firewall is turned on, follow these steps:

  1. Click Startand then click Control Panel.
  2. In the search box in the upper right corner of Control Panel, type security.
  3. In the search results that appear, click the icon or the link to the Security Center. In the window that appears, you will see four bars that are titled firewall, automatic updating, malware protection, and other security settings.
  4. Click the arrow to the right in the firewall bar to expand the bar. The extended bar will display one of the following three options:
    1. If the firewall bar is green, it means that the firewall is enabled.
    2. If the firewall bar is red, you may see a message that the Windows Firewall is disabled. To turn on the Windows Firewall and cause the firewall bar to the center of safety to turn green, click activate now.
    3. If the firewall bar is red, and the message describes a problem with a third-party firewall program, we recommend that you disconnect the computer from the network and then contact the vendor of the firewall program for more information on how to activate the third-party firewall program.
