Ok I want something mask my IP from hackers ect. I saw somethng like that in a topic before but cant remember which one. Something that shows a hacker a false IP and masks your real one. I want this because some of my important ports are open to host games but I want to be secure
check out www.portforward.com if your using a router, this will help you set up a static ip adress, and alloww certain ports, not sure if its exactly what your looking for but it might help
Why not just mask your IP all the time then? May slow your PC down a little, but other than that nothing big. Or if you only need it when you are gaming. Just mask your IP before you start There are many sites with lots of proxys. So just google for them.
If you are doing this just for websites try a site called surfshield. they have some good links and an ip mask for site surfing.
