You'll have to draw your own conclusions.
If you're on the Internet (and not behind a proxy) then you ARE advertising your IP addresses. Sounds like yours may have been found by a random scanner. The good news is that it appears your firewall worked, your internal address was not disclosed. And you wisely posted using a public e-mail service (not your internal network id). Only problem was Yahoo displayed the IP address of the Webmail poster in the message header - it was posted by the host IP 63.163.99.130. The lookup on that is left as an exercise for the reader...
All of the above information is in the public domain and readily available using one or more of the tools that should be in an auditors toolbox.

Subject: Company Firewall's IP Address
I was doing security research on the internet at work yesterday....when all
of
a sudden I got a pop up advertisement that stated that I was broadcasting my
IP
address to the entire internet. It then showed a screen with my IP address
which was the the external IP interface of one of our companies firewalls.
It just bothers me that someone would be able to determine the IP address of
our firewall that easily. It seems to me that our firewall should operate
in a
more stealth mode. Our firewall administrator said it is not technically
possible to do this. What is your take?I am not a checkpoint firewall
guruso
I do not know. All I know is that if I was a hacker, I would love to
hammer
away on an ip address that represented a firewall.
