No one can do anything with just your IP address...
So if you really want them not to give out your IP address, send them a mail.
It will change when it expires.
It could be 24 hours or more or less... Don't worry, as long as you have good anti-virus and Firewall protection, nothing will happen to you. And also nothing can be done with JUST the IP address...
The only way for them to find out your real home address is if the ISP gives it to them.
There is no way to track where you are.
Your ISP won't tell them your address, they might tell the FBI if you did something really illegal. But just on a forum it's nothing to worry about.![]()
You must of really did something stupid, to be so worried.. No they will not lie and make up stories. They will not spoof your IP and pretend like you attacked a government database, nor will they download a self propagating virus to turn your computer into a festering infection. Zonealarm will not protect you if you've done something something stupid and someone subpoena's your ISP to force them to reveal your location, but it will help to prevent anonymous attacks and unwarranted entry. Just don't worry about it, unless it was the secret forum of the Hashishin (Assassin) or something and you insulted their honor, or their mothers. XD
NAT, by default it does not allow remote hosts to connect to your network. Most routers have it, they would have to have access to your router to tunnel through. I wouldn't worry about it. You are more likely to get social engineer anyways.
