DNS server UDP probes & ZA

[doodle]

Hi,

i use ZoneAlarm but i have a problem...
First let me tell you what happens:

From time to time i get alot of port probes from my DNS,
in the last 10 min, for example i got over 100 alerts from zonealarm.-->

The firewall has blocked Internet access to your computer (UDP Port 1302) from xxx.xxx.xxx.xxx (DNS).

(i replaced the DNS' ip )
The ports that were probed range from 1302 up to port 1814
(so over 100 probes in this range)

is this normal ?? that much probes from my dns ?

Shortly after these probes my icq cant reconnect and i can't check my mail, browsing and ftp still work.

But now for my problem:
When i include the dns' IP in the local zone, this problem doesn't go away....

i would verry much appreciate it if somebody told me what's going on here,
thanks.
