Hello. I have a security question.

I recently had a discussion with a friend who
do bittorrent (ZA Pro updated, Windows XP updated).

To make it work, he claims that it is generally nessecary
do the following:

First create an expert firewall rule with the following settings:

Add protocol -> TCP/UDP -> Allow (no log), Enabled

Destination port: Other Any

Source port: Other Any

Next,
create a program expert rule with same settings for
the client.

I said. "Hey : The expert firewall rule you have made

is a bad idea. It really should not be nessecary

for any client. You have lowered your shields far too much".

But is this right? I can see (not beeing behind a router)

that most of my service ports becomes unstealth

if apply the expert firewall rule (i have high security for the internet zone).

And in the manual, i read something about Zone rules being skipped whenever a packet

is allowed by an expert firewall rule. So his expert firewall rule sounds bad to me?

But is that right? I appriciate comments to this.

Best wishes.
