I’m a system administrator for a small business and planning to install Comodo Firewall V3 as personal firewall on all our PC.
It’s very powerful and secure, especially for Defence+, which is one feature that I have never seen before on other free (or pseudo-free) personal firewall.
I’m experiencing only one big trouble: it seem that comodo slow down only some kind of application when this access the network. While apps like thunderbird, firefox and many other tool (we use a lot of SNMP manager, remote VNC access to servers and so on) are not slow down, some application (eg. ConText, FreeCommander, CrossStudio) when used on remote files (across a samba share) slow down a lot (I mean… the stay locked even for nearly a second!!)
I have seen that ConText (which is a text editor) do a lot of samba access when you edit a file, the same when with FreeCommander you switch from a directory to another.
The environment is Windows XP SP2 (32bit) and my samba subnet has been added in “My Network Zone”.
All this applications has been added as “Trusted Application” to firewall/defence+ list.
Another strange thing is that those application slow down even if I shutdown the firewall (by setting it’s level as disable or by closing Comodo application). I have to uninstall and reboot Windows to have “faster” apps.
Any clue?
Do you think I’m missing something in my firewall setup?
Maybe this slow down is only due the fact that those application open a lot of TCP connection to access samba shares? If yes, why does firefox (which open a lot of TCP connection too to access complex web pages) is not affected by this slow down?
Is it possibile to avoid this?
Is it possibile to create a “white list” of application that “bypass” Comodo Firewall?
I think you need someone with a bit more technical knowledge than I have to help you with this. Maybe we can get someone now to look at this for you and see if it can be sorted out.
Have you tried setting the affected applications as trusted applications for the firewall? You may want to look at what the D+ and Firewall logs show wrt those apps. That said, IME, disabling the component seems to fully clear out comodo interfearance in most apps.
I’ve seen programs make Samba share access slower, but not Comodo yet. Then again, I don’t use the above apps. What happens if you copy the file locally and edit?
Yes the affected application was added as “trusted application” in Comodo. BTW setting both Firewall and Defence+ as “Disable” does not change application behaviour. Only by un-installing Comodo (and rebooting the system, of course) those apps become fast as usual.
By using local file I cannot see any performance impact, so only remote editing (on samba share) are affected
Network browsing is not affected (as far as I can see) by this slow down. Anyway I tried to disable WebClient and nothing changed.
Regarding firewall ports: those samba share are on my trusted network and those applications are registred as “trusted application” so all the port should not be filtered (AFAIK)
I am having this same problem, the browsing of my network (samba and windows machines) is terribly slow.
Disabling does not have any effect. A reboot would probably help, but I want to be able to use comodo of course
Is there any official bug report for this, is this at all a new bug since the latest versions? (i just started using comodo recently)
