Did you nmap from behind the packetshaper? Try directly against the pix if
you can.

NMap may be picking up the filtering of the packetshaper

Subject: [fw-wiz] nmap on the internal interface of a PIX


The latest PIX threads got me poking at mine.  When I run nmap
against the internal interface I see:

[dmonjar@monjard ~]$ nmap 10.155.1.49

Starting nmap V. 2.53 by fyodor () insecure org ( www.insecure.org/nmap/ )
Interesting ports on pix.orgtek.com (10.155.1.49):
(The 1515 ports scanned but not shown below are in state: closed)
Port       State       Service
23/tcp     open        telnet
194/tcp    filtered    irc
1467/tcp   open        csdmbase
5631/tcp   filtered    pcanywheredata
5632/tcp   filtered    pcanywherestat
6000/tcp   filtered    X11
6667/tcp   filtered    irc
65301/tcp  filtered    pcanywhere



I get nervous when I see anything with 'pcanywhere' in the string.
Any idea why they're there?  There are no conduits for those ports
configured and I have a filtering device (PacketShaper from Packeteer)
sitting on the internal interface between the PIX and the network that
excplicits discards pcanywhere stuff.
