I am sure you are using either a firewall app or a proxy server to protect
your intranet from the internet, right?

If not, please post the URL of you web server soI can get you fired in about
5 minutes.

Your intranet SHOULD NOT BE ON A LEGAL ROUTABLE NETWORK. That is sheer
lunacy. Put yor intranet on a private network where it belongs and you are
another step closer to keeping your job. When you use a firewall, like
checkpoint, you tell it how to handle inbound traffic. So...when traffic
goes to your 1 legal IP address (the one your ISP gives you) it will look at
the port on which the request is being made. If the call is to port 80 (web
traffic, go to 192.168.0.56, the intranet webserver), if it is 21 (ftp
traffic, send it to 192.168.0.87, the ftp server) you get the idea. It gets
much more complicated from here. Say you have more than one web server, or
you have multiple Exchange bridgehead servers....it gets more tricky. Now
you are getting into scenarios where you need to have your own DNS that
shares the firewall so you can do load balancing with MX records and
stuff.......

Keep it simple. Use a firewall or an application that supports inbound NAT
or proxying, like checkpoint or MS Proxy 2.0.

But if you do nothing else, get your network off the internet....otherwise
you are asking for BIG TROUBLE!


Good luck,

Todd

PS> what was that URL...
