Situation:
Host PC running ICS and install ZoneAlarm Pro version 7.0.462.000.
All clients PC didn't install any Firewall.

Setting:
Firewall=>Internet Zone Security (set to High)
Firewall=>Internet Zone Security=>Custom=>(I already Check "Allow outgoing UDP ports:10101&quot

Problem:
When client pc running p2p program (via port 10101), the Host ZA Log Viewer shown block UDP 10101 outgoing connection.
BUT if when the Firewall=>Internet Zone Security (set to Medium), all the block UDP 10101 outgoing connection will not appear! Another weird situation is, when Firewall=>Internet Zone Security (set to Medium) AND Firewall=>Internet Zone Security=>Custom=>Uncheck (Allow outgoing UDP ports:10101), there is still no blocking UDP 10101 outgoing connection shown in the Log Viewer. So it that mean, by default when Firewall=>Internet Zone Security (set to Medium), it will ALLOW ALL UDP Outgoing Connection?

Question:
Why i already allow outgoing UDP 10101 but ZA still BLOCK IT when Firewall=>Internet Zone Security (set to High)? However the problem gone when Firewall=>Internet Zone Security (set to Medium)??
