Can someone advise me if it’s possible to use Windows Firewall to block a single 
port?  I searched for this over the Internet, but none of the responses addressed 
the issue.  Each time the OP gave an example port to block and the discussion turned 
into ways of blocking the program.

Can someone tell me if it’s possible to block port 80 using Windows’ Firewall.  After 
that I’d like to run on port 80 for example, then block port 81.

If it’s not possible to do this with Windows Firewall, can someone tell me of a very 
simple third party firewall that can easily be installed for the purpose of blocking 
specific ports.

Thanks in advance for any suggestions or comments.

I can only see ways of enabling port. I can’t see any way to block ports. I downloaded the GUI. It appears to be the same way. It seems that you can add ports (as with Windows Firewall) for opening. Is it possible that you can mention steps with Windows Firewall that will block a single port? Port 80 for example? Or is it possible that you can mention steps using the Windows Firewall Port & Application Manager to block a port? Port 80 for example? By the way, this thread isn’t about my intentions in trying to protect a PC, it’s about studying the functionality of various ports. The PC is quite protected. There’s a story behind the stamp on my messages. I kind of hate to distract from learning how to block ports in Windows, since, as I mention I searched the Internet before posting my question. The question is referenced many times, but it’s never answered. The thread always goes into a different direction. Thanks for the input. Thanks also for the suggestion and warning about spam and security. A person practically has to apply for access to get pass my spam filter. -- L. James -- L. D.

If your easier way is a closely guarded secret, I understand your desire not to share, but if it isn’t, I’d appreciate if you can share the information. Since my posting here I downloaded Zone Alarm Firewall. I thought they would have some feature for blocking a port. But the only thing I can find with it is protecting the compute, blocking programs and IP addresses and zones. It shows which ports has been contacted, blocked along with lots of other data information, but I can’t see an option to specifically block a port. If anybody can contribute to this, thanks in advance. If I find a way with any program for Windows I’ll update the topic for others who might want to block a specific port. Thanks in advance for anyone who shares input. -- L. James -- L. D.

I feel it would have been rude of me to the user offering to help and to the group by not reporting back the results. It would appear that the suggestion worked and I was rude not to let anyone know and not to express appreciation. Also, there would be no need for anyone who have input that might actually work to contribute to the topic. In this case, your suggestion doesn’t work. I don’t know what it is that you’re saying you forgot. I don’t know if you’re saying you forgot how to use Windows Firewall, or that you forgot how to use the GUI that you suggested would allow blocking a single port. I asked you how to use the GUI that you say you use, for blocking a single port. I understand that you can’t if you don’t remember (or know how) to use it. I immediately tried your suggestion and it failed as far as I could get. There is a help feature that also doesn’t work. So there isn’t a way to actually figure out how to use the application. I thought you might have considered sharing how you use it to block a port. But again, I don’t mean to be rude. It’s clear that you can’t help if you don’t know how to use it. Also, I’m kind of under the impression that Windows Firewall can’t block a single port. It can only secure the computer and open up specific ports. If that’s the case, having a GUI to control an application that can’t do the task in the first place is almost certainly bound to fail. I believe this information is important to the thread, since the question comes up often as I have mentioned, but so far all the responses are extremely vague. For anyone familiar with Firewalls and Ports, does anyone know of any way, using Windows Firewall or any other application, to block a single port, not by program, but by port number? By the way, I do this all the time with Linux. I use a program called iptables. On that, does anyone know of an application similar to iptables for Windows Vista? Thanks in advance for anyone who has any input on this matter. -- L. James -- L. D.
