Hi, LWM. I wanted to ask you for a favor. I saw the post started by you about ZA Pro 4.0, I think. You said that there are far more configurable firewalls than ZA Pro's Expert rules section. I wanted to ask you if you consider Outpost Pro 2008 more configurable than ZoneAlarm Pro 7.0473.000, what other firewalls besides Jetico2 and Look'N'Stop are more configurable than ZA Pro 7.0.473.000? Since you are much, much more advanced user than I'm, I do have 2 questions: Is the point of firewalls' configuration to make you more secure? Isn't simply enough to have all closed ports from 0 to 65535? Than no hacker will be able to penetrate to your computer. Does more complex firewall configuration make you more secure or is it a waste of time? If you simply block all protocols, ports, IPs, incoming DHCP, TCP, UDP, SMTP, ICMP, IGMP, NetBIOS and the rest of all known protocols in ZA Pro are you completely safe? ZA by default has all ports closed; I think that should be enough protection against hackers although thanks to my 2 years experience I did manage to learn to configure some of these things. Basically, I block absolutely everything inbound and only a few outbound connections are partially allowed (I set rule to "ask"). Also, I've heard from a friend that hackers basically can make completely harmless file which when you open it, gives detailed information to a hacker about your IP, operation system, LAN and etc... I don't think any firewall can do anything at all when something like that happens, not even HIPS... Your opinions highly needed!!!
