Bd Internet Security 2009 - Firewall Problem

Hello Michael,

Do you get any alerts/warnings/messages from BitDefender?

What exactly happens when you say you are "blocked"?

Cris.

Please go to BitDefender Security Center (Advanced) -> Firewall -> Rules and check all rules for firefox.exe to see if anything blocks any traffic.

Also, check the Network tab (in the Firewall) and see what level of Trust is set for your network card.

If you can't find anything blocking access, go to the Activity tab, select Increased Log Verbosity, close the security center, try to access some pages (some pages that are blocked), then go back to the Activity tab and click Show log. Check at the bottom of the log file to see if anything is blocked, and why If anything is blocked by the firewall, it should say something like:

<date/time> <BD filter/module> Blocked packet for / from <something> because of <reason>. Direction: <direction>, Local Address: <IP-port>, Remote Address: <IP-port>, Protocol: <protocol number>, Local Packet: <number>, PID: <PID>, Process: <process>, Cmd. Line: <cmd line>.

Packets blocked because of stealth settings are incoming connections (as seen in the Direction:Inbound parameter, which means "incoming connection"). These packets are blocked by BitDefender because a server tried to access a closed port (in other words, it was an unsolicited packet).

Stealth settings shouldn't affect browsing (or other types of requested network communication) because, as I said, it blocks only unsolicited packets.

Are there any other lines in the log, which show blocked packets from other reasons than "stealth settings"?

If you want to check if "Stealth" is actually the source of your problems, go to Firewall -> Settings -> Advanced settings and uncheck Block port scans. Also, go to Firewall -> Network and set the Stealth setting to Off.

I really don't recommend these settings if you have a direct connection to the internet (as it exposes your computer, making it visible for anyone), but just for the sake of testing disable them for a short time to see if it makes any difference.

Cris.

Disabling the BitDefender NDIS Filter Driver makes the firewall useless, as it won't be capable of filtering any traffic from the network adapter. Please leave that filter enabled, unless you know exactly what you are doing.

Hello lutz,

Well, reinstalling the driver is a little tricky.

First of all, reboot your computer (if you haven't already done so). After that, follow the steps described HERE, with the following observations:

• The two patches are BAT files, which have to be saved into your computer and then ran. To save them right click on the link, and select Save target as
  
• Step E has to be performed in SafeMode. So, at Step D, when you are told to reboot your computer, reboot in SafeMode (reboot, press F8 multiple times during boot, and, when the BootMenu appears, select Safe Mode). After Step E, reboot normally.
• During Step E, Windows might alert you about some unsigned drivers being installed. Click Install anyway (or Continue installation, or whatever the approval message is ).

Cris.

The patches are EXEs, not BATs, but it worked. Everything's running again.

For a very long period of time those patches were BAT files.

Because many users had problems saving/running them, I guess they decided to make the patches EXE files (which I didn't know). Thanks for correcting me.

Could you please give me an answer for another question I asked anywhen: How can I save all my BD TS settings and rules for possible future reinstalls?

2009 versions don't yet have an Import/Export function, unfortunately.

Cris.
