Security test of firewall dose not show UDP port 500 is open

Subject: Security test of firewall dose not show UDP port 500 is open

Hi all,

We have been using Nessus for security scanning the Cisco Pix firewalls we 
install for our custemers. I have one "old" repport showing ISAKMP UDM port 500 
is open. The firewall isn't updated but now the port has disapeard fro the new 
rapport?
We have asked Cisco if the securiyt scanner is supposed to find UDP port 500 (I 
don't think so) and a CCIE from Cisco have told us "no the port is hidden."

I wonder how the port can be in the old repport?

If any one has any input please let me know.

Best regards,

MTK
