My regrets on my message posted on this topic, I misread what you had said, the message is not currently on the list 
yet, but I go on to say your firewall admin is basically incompetent, but apparently, I am :)

I thought you were saying that your fw admin claims there was no way for an external site to obtain the firewall IP.

Sorry again,

|Yes, that is a lousy advertisement designed to panic people into
|stampeding to their site. I got the same message on my home PC. The sad
|fact is that I agree with your IT manager. If you're going to do any
|communication with the world, you have to have someplace for the world
|to send messages to. There has to be an external IP address. What
|Checkpoint does is screen what comes into your organization from your
|external interface. You would have to look at your Checkpoint rule base
|to determine the sites it is blocking, if any. Most organizations let
|email come through the firewall to the corporate users and let them use
|the delete button. There are some commercial services that you can
|subscribe to in order to block categories of sites, but you pay good
|bucks to them for taking your headaches. Yes, this is how worms like
|Klez and viruses get around companies so quickly, but try to sell
|executive management on restricting their email access.
