Hi all,

> From the DMZ (1.0), I ran an nmap scan (-sA switch) towards the subnet
my

noticed the PIX responded with an ip of 10.89.112.1     I dont have a
class
A scheme.  Why is this 10.88.112.1 address showing up from the PIX?


05:10:05.232940 IP (tos 0x0, ttl 254, id 39360, offset 0, flags [none],
proto: ICMP (1), length: 56) 10.89.112.1 > 192.168.1.5: ICMP host
192.168.2.1 unreachable - admin prohibited filter, length 36
