I am new here and would like to ask a question about Comodo Firewall functionality. I’d like to try Comodo Firewall but couldn’t find the infromation if it will work for my network setup. Here is the info I’m looking for:
I have my ADSL adapter in bridge mode and Windows computer making the connection over dial-up (PPPoE). In my network there is also a Linux server with static local IP address.
Since my Windows firewall is in fact acting as a router, I set the option in Windows firewall to forward all incoming traffic on port 80 to the static local IP address of the Apache server on Linux machine.
The question is: Shall I be able to achieve the same after installing Comodo Firewall and disabling the built-in Windows firewall?
Assuming that your Windows box is a pseudo-router for your LAN, what you want to achieve is relatively easy.
You would need to create a Global Rule with the following parameters;
Action : ALLOW
Protocol : TCP or UDP
Direction : IN
Description : Something relevant to you
Source Address : ANY
Destination : Internal IP address of your Apache server
Source Port : Type - Any
Destination Port : Type - A Set of Ports → Ports - HTTP Ports
NOTE : “HTTP Ports” is predefined to include ports 80, 8080 and 443. If you only need port 80, your destination port setting would be
Destination Port : Type - A Set of Ports → Ports - A single port → Port - 80
If it all works, could you please post back here with the results and any modifications you made to suit your environment, in case it could help others in the future.
unfortunately I am writing this from another OS because Comodo Firewall freezes the PC and I cannot uninstall it. I searched Google with the search string:
comodo firewall freezes computer
and there is a lot of posts describing the very same problem (e.g. this thread). Can you please provide the details on how I can uninstall Comodo Firewall manually because the (un)installer cannot be run in the safe mode and CF freezes the computer if started normally? I believe removing some Registry key(s) or even .exe file while in the Safe Mode would prevent Comodo Firewall from starting so I could run the unistaller but I wouldn’t like to remove the key(s)/files on my own.
I really would like to avoid using System Restore so I am looking for some other way of uninstalling the firewall. According to the other posts describing the same problem I am assuming the problem could be the conflict between my antivirus SW (AVG) and Comodo Firewall?
After reading through hundreds of the posts all of them describing always one and the same problem (computer freezes after installing Comodo Firewall, can’t unistall) I have to say the note printed with the big red letters saying: **** CAUTION!!! ****
Before installing the product, backing up of the complete system is not just recommended but mandatory since there is quite a big chance that after installing the firewall your system would not be anymore operable and there isn’t a way to uninstall the Comodo Firewall in a clear and straightforward way! Install this software if and only if it is going to be the ONLY ONE security software installed in your computer!
should be clearly displayed and the buttons:
Do you want to proceed anyway?
and
Are you sure?
should be implemented as safety measure!
I just couldn’t believe when I saw this is the way to ‘uninstall’ the software!? Not to mention the described process can be used only with older versions.
If someone is interested - the only way so I could use my computer again was to enter Safe Mode and edit the Registry to prevent launching of .exe and then (after restart) using System Restore to go back to the state before I installed the Comodo Firewall (which took me 7 hours).
Every software should have an uninstaller that is capable of uninstalling it in the case the user decides they want to remove the program. Especially if the software is known for completely freezing the computer and making the OS inoperable.
Well, that couldn’t help me because I installed the latest version. A I said:

When I disabled AVG antivirus and launched Comodo Firewall manually then it worked. If I then re-enabled AVG it couldn’t work although I allowed every AVG process when firewall asked and after a few minutes computer froze as well.
From what I saw during the time when firewall was active (when AVG was disabled) I can say it is a very sofisticated product and has outstanding capabilities for capturing and analysing network threats, but it really should be able to cooperate with other software. I know more than one antivirus product cannot work in the same time but what I need is a firewall and not another anitivirus software.
I believe additional Comodo Firewall modules (beyond firewall) could be disabled so the firewall could work along with antivirus software(s) such AVG but I also have a feeling it integrates too deeply in the OS.
The main reason I uninstalled the Comodo Firewal (and didn’t try to tweak the options so it could work with AVG) is because forum posts suggest that updates sometimes can break the functionality and updating to the new major version requires removing the former version - which looks like more than tedious work with no guarantee the process will be successful, so there would always be a risk of having to reinstall the OS.
Hi Guys,
You know what I don’t get.
When there is a software conflict between Comodo and another product, why is it always Comodo at fault? ???
After all it takes two to tango.
I don’t know for the others but here is my point of view:
#1
If there are programs A, B, C, D, E and F and {A, B, C, D, E} works well in any combination of installed subsets but program F is causing freeze in combination with more than one program from the set {A, B, C, D, E} then I see program F as the problem and not {A, B, C, D, E}.
#2
Before I installed Comodo Firewall everything was working for years but after installing CF I couldn’t anymore use my PC.
I meant including the latest version in case my phrasing was not clear.
When I disabled AVG antivirus and launched Comodo Firewall manually then it worked. If I then re-enabled AVG it couldn't work although I allowed every AVG process when firewall asked and after a few minutes computer froze as well.

To try to solve possible compatibility issues try adding the installation folder of AVG to the Exclusions of Detect shellcode injections. Also try adding the CIS installation folders to the Exclusions of AVG.
All security programs integrate deep in the OS without exceptions and might bite at each other because of that. It’s not an indication of quality of the software involved when this happens. There is always a slight change an update might break something but those are very slim chances that I would not focus on as it may happen to any software.
Reinstalling the OS is a last resort. What always works is go to Safe Mode and disable the autostarts of an offending program using for example Autoruns. That will allow you to easily boot back into Windows and start the uninstaller from there. But the clean up tool will also do the job for you. An official clean up tool by Comodo has been requested many times but has not surfaced yet.
