I'm going thru a great learning curve in understanding how firewalls work. I believe that I have captured the basics. I would like to tighten the security on my firewall (currently using Kerio 4 but would like to use 2.15)
I still have some problems with some basic applications. The way I try to tighten the rules is to ask first and then set an advanced filter rule. However in the example of outlook 2003 once I went thru a successful startup of outlook and had set all filter rules it worked well. It only needed access for port 110 and 80 to the internet and another half a dozen ports (1800- 1850) in the trusted area.
Would the statement be correctly that the trusted area is your local area network only???
Now everytime I restart outlook it will ask me to open new ports that where previously blocked, I ended up with an etxra 10 or more ports and finally gave up to allow full access.
This also applies to some other applications.
Looks like I still need soome serious help. Can anybody shed some light on this issue I have.
Thanks in advance

BAd idea. Allowing remote outbound to port 80 for any email client. It leaves you vulnerable to web bugs.
