Just tried PE demo and I'm very impressed. I have a question though. I'm using the Kerio firewall (WIN 95, rules block everything not explicitly allowed by a previous rule). I did not get any alerts from Kerio while using PE even though I did not make any rule to allow it. Is that because it does not open/use any ports or does it somehow bypass Kerio? It seems to work fine but I just want to understand what is going on before I decide to register it/keep it. Thanks.
