Today I opened my PC and I was unable to connect to the internet… After several tests, I discovered that Comodo firewall was blocking all my traffic (http, e-mails, eMule, MSN messenger, everything. I was not able to access my aDSL modem’s interaface via web-browser as well!).
I checked the firewall’s settings and nothing has been changed… All of a sudden, the firewall has cut everything!! When I sellect “Allow all” everything works normaly, but when I switch back to “Custom” protection everything is blockd ??? ???
Do you have any idea? I have Comodo Personal Firewall v126.96.36.199 and I also run Kaspersky Antivirus, Peer Guardian and the hardware firewall from my DSL modem (USR 9105).
Hi digibill, welcome to the forums.
Sorry, you’re having problems. Please check CPFs Log (Activity tab). If CPFs blocking something, then it should logged in the Log. It will record which part of CPF is causing the block & what is exactly being blocked.
Well, I see that for every block the reason is “Network Control Rule ID = 8”. This network rule is the last one in the network rules tab, that blocks every traffic and -as far I know- is responsible for blocking everything else that does not meet the criteria in the above rules… But, this is supposed to be last in priority, right? ??? Then, why it overpasses all the above rules and blocks everything?
(I haven’t changed anything in the network rules!!)
Thanks for the help Kail :■■■■
That is very strange. Can you please post a screen shot of your Network Rules (with the screen maximized). Also since there are so many Log entries can you right click the Log, select Event Logs From & deselect the Component Monitor. This is just a temporary thing to see if there any other hidden messages, you can reselect straight afterwards. Thanks.
Also, has anything major happened on your system since the last time you had successfully used your Internet connection? Installed any programs? Any problems, errors, etc…?
Well, here is the screenshot…
I also tried this:

…all the messages are from the network monitor :
Nothing has changed in my system since the last time that everything was working fine… I just shut down my PC and in the next startup everything was blocked!!

Wow… your Network Monitor rules are an utter mess. Do you know if they have always been like this?
Anyway… it looks like the CPF installation might have been corrupted. The Network Monitor rules are stored in the Registry and since they should be protected by CPF, I’ve no idea what has happened. If you’re on XP consider trying a restore to a known point when CPF was OK. Otherwise, or if the restore fails, then you should uninstall & re-install CPF to correct this problem.
Well, by default CPF creates 5 rules and I’ve also added 2 rules for eMule and 1 for mjuTorrent… So, this is how they always were… :

I tried several restores but none worked… So, I reinstalled CPF and now it works just great (as it used to ;D )
Thanks for the help :■■■■
i also noticed this behavior. with default settings.
however i believe this happened after setting “stop connections until cpf runs” rule, because i think this is related with some UI problem. i couldnt access tray right click menu, so i clicked on desktop link and i get into main window, but i was unable to change settings, so it jammed all connections…
i had to uninstall and go back to stable version. (:SAD)
