Take a look at this:

Also, if you've disabled packet filtering, you're wide open to the world.

Subject: [isalist] Strange connections reported by netstat
http://www.ISAserver.org
Hi, all !
I scanned my ISA external interface for open ports and I noticed that
since last scan, 2 ports appear as open: 135 and 443.
Issuing a netstat -an, I noticed these connections:
UDP 0.0.0.0:37 *:*
UDP 0.0.0.0:123 *:*
UDP 0.0.0.0:135 *:*
UDP 0.0.0.0:445 *:*
UDP 0.0.0.0:3003 *:*
UDP 0.0.0.0:3005 *:*
UDP 0.0.0.0:3456 *:*
UDP 0.0.0.0:3457 *:*
UDP 0.0.0.0:17953 *:*
UDP 0.0.0.0:18137 *:*
UDP 127.0.0.1:53 *:*
UDP 127.0.0.1:3004 *:*
Are they normal connections ? I guess not.
How can get rid of these and eventually closing those ports.
Initially, I had only 2 ports open: 25 and 80.
TIA,
Alin
