Personal Firewall

Oh yes, the Internet rocks. At least for people who use it „safely“. Safer networking seems to be a very difficult thing for adolescents or older persons. I’ve seen many people surfing without these neat applications. Yes, I am talking about personal firewalls. I don’t want to start a discussion about the sense of these programs or how to use them. In fact I am using this software only to permit access to any network from applications I personally installed on my PC (I have a better firewall within my router, it uses IP filtering with ip-tables).

In the past I used the personal firewall of Sygate. However that application is no longer maintained or updated, because Symantec decided to continue only the professional branch of Sygates software development. Because of that and the fact that I formatted my HDD last week, I had to look for an alternative. I made my choice and ended up with the Kerio Personal Firewall. At first I was satisfied with my decision. Sadly enough I had to learn, that I made the wrong decision, especially within the last few days. Althoug I could set network access rights for started programs (both inbound and outbound traffic), there was no method of defining these parameters for yet not startet programs. That is why you can setup an FTP server for example but cannot access it from without the network, because the dialog for (firewall) configuration for access rights pops up if you try to login for the first time.

Moreover I noticed some kind of strange behaviour as for the Windows Explorer (I don’t talk about the wellknown „strange“ behaviour, to the Linux nerds: just shut up, I do not want to hear it). Within the first 5 minutes after restarting my system, I could not start the Explorer with the shortcut Win (Windows Key) + E. If I did this, my taskbar completely hung up and programs could only be started via the Task Manager. This hanging lastet for about 45 seconds and afterwards everything worked just normal again. Even the shortcut for starting an Explorer window worked perfect. That is why I installed all possible Windows Updates and optimizations (German) as well as the up to date AMD drivers, because I thought it was an issue with Dual Core CPUs. Unfortunately the misbehaviour did not went away. The I decided to deactivate some Windows services and all start-up applications. Step after step I reactivated services and applications with a restart for each. Everything worked just fine, until I re-installed the firewall service. The Explorer hung up again. Conclusion: I am looking for a new personal firewall.
