Your admin is right. In order for you to be able to pull data from the Internet, or any other system connected via a network, you have to give the destination system an address to reply to, hence your IP address. Knowing the IP address of your firewall is not a major issue, not if your firewall is configured correctly. A hacker can find IP addresses all day long. There are only so many addresses, and with a little programming, he can scan a specific range of addresses, which are public knowledge BTW, and find openings in an improperly configured system.

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.
