Precisely, unless of course you DO have a static IP address, and someone who knows it is specifically trying to get past your firewall, which unfortunately, some are skilled enough to do. Sometimes. Most DSL subscribers who have a static IP address know it, since you have to pay considerably more to have one. In my case, simply disconnecting (via the modem software) from the 'net, then reconnecting results in a new IP assignment. I don't mean to pick on anyone but post #2 in this thread doesn't make sense. There's nothing in DarkMatter's description that would indicate the scenario asserted in that post. SPAM spoofing is a real problem these days, but there wasn't enough relevant info provided to draw that conclusion, here. C'mon, folks, if you don't really know for sure what you're talking about in threads like this, don't speak with seeming authority. It causes confusion and spreads misinformation. ...and of course, JohnRender is correct :-)
